__TOC__
Comme Mac OS X est basé sur la distribution''' BSD (UNIX)''', la compilation de FreeCAD sur '''Mac''' n'est pas très différente de [[CompileOnUnix/fr|CompileOnUnix]], mais il existe cependant un certain nombre de détails très importants, spécifiques au Mac, pour que tout fonctionne correctement. Ces instructions ont été testées sur '''Lion (10.7)''', mais ''devrait fonctionner'' sur les '''Macs Intel''' qui utilisent '''(Snow) Leopard'''.


This page describes how to compile the latest FreeCAD source on macOS X. ''Latest'' means the most recent commit to the master branch of the FreeCAD github repository.
== Obtenir le code source ==


These instructions have been tested on macOS High Sierra
Avant de compiler FreeCAD, vous avez besoin du code source. Il y a trois moyens de l'obtenir :


This page serves as a quick start, and is not intended to be comprehensive with regard to describing all the available build options.
=== Git ===


If you just want to evaluate the latest pre-release build of FreeCAD, you can download pre-built binaries [https://github.com/FreeCAD/FreeCAD/releases from here].
La méthode la meilleure et la plus rapide d'obtenir le code est de « cloner » le dépôt Git en lecture seule (il vous faut le paquet [http://git-scm.com/ git] installé):


== Install Prerequisites ==
git clone git://free-cad.git.sourceforge.net/gitroot/free-cad/free-cad freecad
The following software must be installed to support the build process.


=== Homebrew Package Manager ===
Ceci place une copie de la plus récente version du code source de FreeCAD dans un nouveau répertoire nommé « freecad ». La première fois que vous vous connectez à l'hôte free-cad.git.sourceforge.net, vous obtiendrez un message vous demandant d'authentifier la clé SSH de Sourceforge. Celle-ci peut normalement être acceptée sans danger (vous pouvez vérifier les clés SSH de Sourceforge sur leur site Web si vous voulez vous en assurer)
Homebrew is a command line based package manager for macOS. The [https://brew.sh/ Homebrew main page] provides an installation command line that you simply paste into a terminal window.


=== Gihub ===
=== CMake ===
CMake is build tool that generates a build configuration based on variables you specify. You then issue the 'make' command to actually build that configuration. The command-line version of CMake is automatically installed as part of the Homebrew installation, above. If you prefer to use a GUI version of CMake, you can download it from [https://www.cmake.org/downloadDownload here].


== Install Dependencies ==
Il y a également une copie synchronisée régulièrement du dépôt FreeCAD sur GitHub :
FreeCAD maintains a Homebrew 'tap' which installs the required formulas and dependencies. Issue the following brew commands in your terminal.
[https://github.com/FreeCAD/FreeCAD_sf_master github.com/FreeCAD/FreeCAD_sf_master]


<br />
=== Paquet source ===
<pre>
brew tap freecad/freecad
brew install eigen
brew install --only-dependencies freecad --with-packaging-utils
</pre>
Notes:
# 'brew install' may take quite a while, so you may want go grab a beverage. :-)


== Get the source ==
Vous pouvez également télécharger un paquet source, mais celui-ci pourrait être assez vieux ; il est donc préférable de télécharger les sources les plus récentes via git ou github. Dépendant de votre distribution, il y a plusieurs façons d'obtenir un paquet source :
In the following instructions, the source and build folders are created side-by-side under


/Users/username/FreeCAD
Paquets source FreeCAD officiels (indépendants des distributions): https://sourceforge.net/projects/free-cad/files/FreeCAD%20Source/
Debian : http://packages.debian.org/source/sid/freecad
Ubuntu : http://packages.ubuntu.com/source/precise/freecad


but you can use whatever folders you want.
=== Dépendances de l'installation ===
<pre>
mkdir ~/FreeCAD
cd ~/FreeCAD
</pre>
The following command will clone the FreeCAD git repository into a directory called FreeCAD-git.
<pre>
git clone https://github.com/FreeCAD/FreeCAD FreeCAD-git
</pre>
Create the build folder.
<pre>
mkdir ~/FreeCAD/build
</pre>
<br />


== Run CMake ==
Sur '''Mac OS X 10.7''', les dépendances suivantes ne sont pas fournies avec le système, et '''doivent''' donc être installées '''avant''' la compilation de FreeCAD :


Next, we will run CMake to generate the build configuration. Several options must be passed to CMake. The following table describes the options and gives some background.
*sip
*fortran
*xerces-c
*boost
*eigen
*ftgl
*coin3d
*OpenCASCADE
*Qt
*pyqt
*soqt


==== Option 1: Homebrew ====
=== CMake Options ===

'''PS :''' cette section est toujours en cours d'élaboration ! Lisez le post sur ​​le forum d'aide pour plus d'informations.
|-
! Name !! Value !! Notes
|-
| CMAKE_BUILD_TYPE || Release (STRING) || Release or Debug. Debug is generally used for developer-level testing but may also be required for user-level testing and troubleshooting.
|-
| BUILD_QT5 || 1 (BOOL) || Required to build with Qt5.
|-
| CMAKE_PREFIX_PATH || "/usr/local/Cellar/qt@5.6/5.6.2/lib/cmake" (PATH) || Required to build with Qt5. See note below.

<pre>
ls -d $(brew list -1 | grep qt | tail -1 | xargs brew --cellar)/*/lib/cmake
</pre>


=== CMake GUI ===
:http://mxcl.github.com/homebrew/
Open the CMake app, and fill in the source and build folder fields. In this example, it would be '''/Users/username/FreeCAD/FreeCAD-git''' for the source, and '''/Users/username/FreeCAD/build''' for the build folder.


Next, click the '''Configure''' button to populate the list of configuration options. This will display a dialog asking you to specify what generator to use. Leave it at the default '''Unix Makefiles.''' Configuring will fail the first time because there are some options that need to be changed. Note: You will need to check the '''Advanced''' checkbox to get all of the options.
Puis, compilez et installez la plupart des dépendances de FreeCAD :


Set options from the table above, then click '''Configure''' again and then '''Generate'''.
brew install sip gfortran xerces-c boost eigen coin qt pyqt soqt ftgl
=== CMake command line ===
Enter the following in the terminal.
<pre>
$cd ~/FreeCAD/build
$cmake \
-DCMAKE_BUILD_TYPE="Release" \
-DBUILD_QT5=1 \
-DCMAKE_PREFIX_PATH="/usr/local/Cellar/qt@5.6/5.6.2/lib/cmake" \
-DFREECAD_USE_EXTERNAL_KDL=1 \
-DBUILD_FEM_NETGEN=1 \
-DFREECAD_CREATE_MAC_APP=1 \
-DCMAKE_INSTALL_PREFIX="./.." \
../FreeCAD-git/


</pre>
Lisez le paragraphe [[CompileOnMac/fr#Compiler OpenCASCADE]].


== Run make ==
==== Option 2: MacPorts/Fink ====
Finally, from a terminal run '''make''' to compile and link FreeCAD, and generate the app bundle.
<pre>
cd ~/FreeCAD/build
make -j5 install
</pre>
The -j option specifies how many make processes to run at once. One plus the number of CPU cores is usually a good number to use. However, if compiling fails for some reason, it is useful to rerun make without the -j option, so that you can see exactly where the error occurred.


See also [[Compiling_(Speeding_up)|Compiling - Speeding up]].
'''PS : cette section a besoin d'être documentée !'''


If make finishes without any errors, you can now launch FreeCAD by double clicking the executable in the Finder.
Installez''' MacPorts''', si vous ne l'avez pas déjà fait. '''MacPorts''' est un système qui vous permet de télécharger, compiler et installer de nombreuses applications open-source en une seule commande. Des applications similaires issues du monde '''Unix/Linux''' sont, '''[http://netbsd-france.org/docs/software/packages.html PKGSRC]''' et '''[http://fr.wikipedia.org/wiki/Advanced_Packaging_Tool APT]'''. Pour l'installer, il suffit de télécharger l'image disque à partir du site '''MacPorts''', et suivez les instructions :


== Updating from Github ==
:http://www.macports.org/install.php
FreeCAD development happens fast; every day or so there are bug fixes or new features. To get the latest changes, use git to update the source directory (see [[Source code management]]), then re-run the CMake and make steps above. It is not usually necessary to start with a clean build directory in this case, and subsequent compiles will generally go much faster than the first one.


== Building with Qt4 ==
Que vous ayez ou non installé '''[http://www.macports.org/ MacPorts]''', vous voudrez probablement vérifier s'il est à jour.<br>
FreeCAD has transitioned from Qt 4 to Qt 5. If you need to build with Qt4, the following additional steps are required.
Exécutez :


# Append '--with-qt4' to the 'brew install' command.
sudo port selfupdate
# Do not specify BUILD_QT5 CMake option.
# Do not specify CMAKE_PREFIX_PATH CMake option


After you install Qt4, if you want to switch to building with Qt5, you will need to uninstall Qt4.
Maintenant que '''[http://www.macports.org/ MacPorts]''' est installé, et à jour, vous pouvez commencer l'installation de certains des paquets nécessaires à FreeCAD :
<pre>
brew uninstall --ignore-dependencies --force cartr/qt4/shiboken@1.2 cartr/qt4/pyside@1.2 cartr/qt4/pyside-tools@1.2 cartr/qt4/qt
</pre>


== Troubleshooting ==
*xercesc
*boost
*py-sip
*ftlg
*f2c
*eigen3
*py-pyqt4
*Coin


=== Segfault on Qt5 launch ===
La commande suivante compile/installe les bibliothèques ci-dessus. Si '''MacPorts''' produit des erreurs, vous pouvez essayer d'installer ceci, '''un à la fois'''.
If Qt4 was previously installed via brew, and you then build with Qt5, you may get a EXC_BAD_ACCESS (SEGSEGV) exception when launching the new Qt5 build. The fix for this is to manually uninstall Qt4.
<pre>
brew uninstall --ignore-dependencies --force cartr/qt4/shiboken@1.2 cartr/qt4/pyside@1.2 cartr/qt4/pyside-tools@1.2 cartr/qt4/qt-legacy-formula
</pre>


=== Fortran ===
sudo port install xercesc boost ftgl f2c eigen3 py-sip py-pyqt4 Coin
''"No CMAKE_Fortran_COMPILER could be found."'' during configuration - Older versions of FreeCAD will need a fortran compiler installed. With Homebrew, do "brew install gcc" and try configuring again, giving cmake the path to Fortran ie -DCMAKE_Fortran_COMPILER=/opt/local/bin/gfortran-mp-4.9 . Or, preferably use a more current version of FreeCAD source!


=== OpenGL ===
Notez, que pour les paquets Python comme '''[http://www.riverbankcomputing.com/software/sip/download py-sip]''' et '''[http://guide.macports.org/ py-pyqt4]''', il ya plusieurs packages, une pour chaque version de '''Python MacPorts'''.<br>
See [[OpenGL_on_MacOS|OpenGL on MacOS]] for OpenGL issues when Qt 4.8 and earlier are used on MacOS.


=== FreeType ===
Notez que '''[http://www.boost.org/ boost]''' est un gros paquet, et '''[http://guide.macports.org/ py-pyqt4]''' dépend '''[http://www.qtcentre.org/wiki/index.php?title=Installing_Qt4_on_Mac_OS_X qt4-mac]''', qui est aussi un gros paquet. Vous pouvez exécuter '''run port -v''' de manière à avoir une idée de ce qui se passe au cours de ces longues compilations.
When using CMake versions older than 3.1.0, it's necessary to set CMake variable FREETYPE_INCLUDE_DIR_freetype2 manually, eg /usr/local/include/freetype2
[http://qt.nokia.com/downloads/ Qt4] est également disponible pour Mac comme un installateur binaire à partir du site Web de [http://qt.nokia.com/downloads/ Qt].<br>
Je ne suis pas sûr, de savoir comment ce passe cette approche avec la compilation de FreeCAD.<br>
Il est également possible de choisir la version du compilateur '''gcc''' à utiliser, certaines versions récentes peuvent parfois provoquer des problèmes :


{{docnav/fr|[[CompileOnUnix/fr|CompileOnUnix]]|[[Third Party Libraries/fr|Third Party Libraries]]}}
sudo port -v install gcc_select
sudo port select --list gcc
sudo port select --set gcc mp-gcc46


{{Userdocnavi}}
'''Installer le Compilateur Fortran'''


[[Category:Developer Documentation/fr]]
Vous avez également besoin d'un compilateur [http://fr.wikipedia.org/wiki/Fortran FORTRAN]. Le fork '''[http://fr.wikipedia.org/wiki/GNU_Compiler_Collection gcc]''' d'Apple sur '''[http://fr.wikipedia.org/wiki/OS_X OSX]''' ne convient pas à FORTRAN.


{{clear}}
Un installateur pour '''GFortran''' peut se trouver ici, et fera l'affaire :

http://gcc.gnu.org/wiki/GFortranBinaries#MacOS

Si vous utilisez '''fink''', une autre méthode consiste à utiliser les commandes suivantes (tenté par Shaneyfelt 2100.Nov.14)
sudo fink selfupdate
sudo fink install gcc46

''Cela installe une autre collection de compilateurs '''gcc''' avec comme nom, '''gcc-4''' afin d'éviter un conflit de nom avec l''''Apple one'''.''

Les paquets '''MacPorts gcc4x''', également incluent les compilateurs de '''Fortran''', et il faudrait également faire :

sudo port install gcc46

Un autre paquet possible pour '''MacPorts''' est '''[http://www.g95.org/ g95]'''.<br>
Cela semble être valable pour le compilateur [http://en.wikipedia.org/wiki/Fortran#Fortran_90 FORTRAN90] et passer des tests de configuration cmake de FreeCAD, mais la version actuelle semble demander des options spécifiques pour '''gcc''', il est sans doute plus facile de s'en tenir à '''[https://trac.macports.org/ticket/33963 gcc4x]'''.

'''Installer Eigen3'''

Téléchargez et décompressez la dernière bibliothèque '''eigen3''' ici :

http://eigen.tuxfamily.org/index.php?title=Main_Page

Ces mesures sont nécessaires pour la fonctionnalité du solveur. Une fois décompressé, le dossier nommé '''Eigen''' peut être déposé dans :

'''/usr/local/include/eigen3/'''

=== Compiler OpenCASCADE ===

Actuellement, la meilleure façon de compiler '''OpenCASCADE''' sur '''OS X''' est, l'édition communautaire ('''OCE''').<br>
Téléchargez le code source ou, consultez le dépôt [http://fr.wikipedia.org/wiki/Git Git] à partir de :

:https://github.com/tpaviot/oce

Alors, tapez dans le terminal :

mkdir build
cd build
cmake ..
cd ..
make
make install/strip

Vous devrez peut-être faire cmake :

sudo port install cmake

=== Télécharger et installer le modèle FreeCAD.app ===

L'archive suivante contient un modèle d'application pour FreeCAD. Ce n'est pas réellement nécessaire, mais il rend le travail de configuration de l'installation par défaut de FreeCAD plus pratique. L'emplacement recommandé de l'installation pour le bundle, est le dossier d'applications, mais vous devriez être en mesure de l'installer où vous voulez. Rrappelez-vous juste que, le faisceau (bundle) '''ne peut pas être déplacé ou modifié''' après que FreeCAD soit installé.<br>
Lancer '''make install''' dans l'étape suivante en utilisant cette configuration, l'installera dans cet ensemble (bundle).

:http://dl.getdropbox.com/u/103808/FreeCAD/FreeCAD_bundle_template_20091128.tar.gz

=== Compilation ===

Configurez, compilez et installez FreeCAD, en utilisant les commandes suivantes à partir du dossier racine de FreeCAD.<br>
Si vous mettez votre paquet '''FreeCAD.app''' ailleurs que dans Application (ou, n'utilise pas le bundle), changer la valeur de '''PREFIX''' en conséquence.

./autogen.sh
PREFIX=/Applications/FreeCAD.app/Contents

Si vous avez installé les dépendances en utilisant l'option '''1 (Homebrew)''' :<br>
'''PS : cette ligne de configuration n'a pas été vérifiée et peut contenir des erreurs !'''

./configure --with-xercesc-lib=/usr/local/lib --with-xercesc-include=/usr/local/include \
--with-boost-lib=/usr/local/lib --with-boost-include=/usr/local/include \
--with-qt4-dir=/usr/local--with-qt4-lib=/usr/local/lib --with-qt4-include=/usr/local/include \

--datarootdir=/Applications/FreeCAD.app/Contents/Resources/share --enable-debug=no \
--with-python-include=/System/Library/Frameworks/Python.framework/Versions/2.5/Headers

ou, si vous avez installé les dépendances en utilisant l'option '''2 (MacPorts/Fink)''' :

./configure --with-xercesc-lib=/opt/local/lib --with-xercesc-include=/opt/local/include \
--with-boost-lib=/opt/local/lib --with-boost-include=/opt/local/include \

--with-qt4-include=/usr/local/Trolltech/Qt-4.8.0/include --with-qt4-framework=/Library/Frameworks \
--with-qt4-bin=/usr/local/Trolltech/Qt-4.8.0/bin --with-occ-lib=/usr/local/lib \
--with-occ-include=/usr/local/include/oce --with-coin=/Library/Frameworks \

--datarootdir=/Applications/FreeCAD.app/Contents/Resources/share --enable-debug=no \
--with-python-include=/System/Library/Frameworks/Python.framework/Versions/2.5/Headers

alors :
make
make install

Selon la puissance de votre machine, l'étape '''make''' peut prendre plus ou moins de temps.

=== Exécution ===

Si tout s'est bien passé, double-cliquez sur ​​le paquet '''.app''' pour démarrer FreeCAD.<br>
Si vous avez des questions, postez les sur le [http://www.freecadweb.org/forum/viewforum.php?f=4 forum d'aide] (Anglais).<br>
Une discussion a été ouverte en Français [https://www.freecadweb.org/forum/viewtopic.php?f=12&t=3538 Freecad sur Mac]

=== PyQt4 ===

Certains utilisateurs ont signalés un message '''"No module named PyQt4"''' au démarrage de FreeCAD.<br>
Il y, a une solution de contournement pour le corriger :

cd /Library/Python/2.6/site-packages
sudo ln -s /contrib/lib/python2.6/site-packages/PyQt4 .
sudo ln -s /contrib/lib/python2.6/site-packages/sip* .
cd /volatile/FreeCAD-r5443-ser/bin/pivy
cp _coin.dylib _coin.so
cd /volatile/FreeCAD-r5443-ser/lib
for i in *.dylib; do j=`basename $i .dylib`; cp $i $j.so; done

=== Pivy ===

Certains composants de FreeCAD ne fonctionneront pas sans pivy. Allez voir [[Extra_python_modules/fr#Pivy|sur cette page]] pour les instructions de compilations partielles.

CompileOnUnix
Compiling (Speeding up)

This page describes how to compile the latest FreeCAD source on macOS X. Latest means the most recent commit to the master branch of the FreeCAD github repository.

These instructions have been tested on macOS High Sierra

This page serves as a quick start, and is not intended to be comprehensive with regard to describing all the available build options.

If you just want to evaluate the latest pre-release build of FreeCAD, you can download pre-built binaries from here.

Install Prerequisites

The following software must be installed to support the build process.

Homebrew Package Manager

Homebrew is a command line based package manager for macOS. The Homebrew main page provides an installation command line that you simply paste into a terminal window.

CMake

CMake is build tool that generates a build configuration based on variables you specify. You then issue the 'make' command to actually build that configuration. The command-line version of CMake is automatically installed as part of the Homebrew installation, above. If you prefer to use a GUI version of CMake, you can download it from here.

Install Dependencies

FreeCAD maintains a Homebrew 'tap' which installs the required formulas and dependencies. Issue the following brew commands in your terminal.


brew tap freecad/freecad
brew install eigen
brew install --only-dependencies freecad --with-packaging-utils

Notes:

  1. 'brew install' may take quite a while, so you may want go grab a beverage. :-)

Get the source

In the following instructions, the source and build folders are created side-by-side under

/Users/username/FreeCAD

but you can use whatever folders you want.

mkdir ~/FreeCAD
cd ~/FreeCAD

The following command will clone the FreeCAD git repository into a directory called FreeCAD-git.

git clone https://github.com/FreeCAD/FreeCAD FreeCAD-git

Create the build folder.

mkdir ~/FreeCAD/build


Run CMake

Next, we will run CMake to generate the build configuration. Several options must be passed to CMake. The following table describes the options and gives some background.

CMake Options

Name Value Notes
CMAKE_BUILD_TYPE Release (STRING) Release or Debug. Debug is generally used for developer-level testing but may also be required for user-level testing and troubleshooting.
BUILD_QT5 1 (BOOL) Required to build with Qt5.
CMAKE_PREFIX_PATH "/usr/local/Cellar/qt@5.6/5.6.2/lib/cmake" (PATH) Required to build with Qt5. See note below.
FREECAD_CREATE_MAC_APP 1 (BOOL) Create a FreeCAD.app bundle at the location specified in CMAKE_INSTALL_PREFIX, when the 'make install' command issued.
CMAKE_INSTALL_PREFIX "./.." (PATH) Path where you want to generate the FreeCAD.app bundle.
FREECAD_USE_EXTERNAL_KDL 1 (BOOL) Required.
BUILD_FEM_NETGEN 1 (BOOL) Required.

Note: Command line to generate CMAKE_PREFIX_PATH:

ls -d $(brew list -1 | grep qt | tail -1 | xargs brew --cellar)/*/lib/cmake

CMake GUI

Open the CMake app, and fill in the source and build folder fields. In this example, it would be /Users/username/FreeCAD/FreeCAD-git for the source, and /Users/username/FreeCAD/build for the build folder.

Next, click the Configure button to populate the list of configuration options. This will display a dialog asking you to specify what generator to use. Leave it at the default Unix Makefiles. Configuring will fail the first time because there are some options that need to be changed. Note: You will need to check the Advanced checkbox to get all of the options.

Set options from the table above, then click Configure again and then Generate.

CMake command line

Enter the following in the terminal.

$cd ~/FreeCAD/build
$cmake \
  -DCMAKE_BUILD_TYPE="Release"   \
  -DBUILD_QT5=1                  \
  -DCMAKE_PREFIX_PATH="/usr/local/Cellar/qt@5.6/5.6.2/lib/cmake"  \
  -DFREECAD_USE_EXTERNAL_KDL=1   \
  -DBUILD_FEM_NETGEN=1           \
  -DFREECAD_CREATE_MAC_APP=1     \
  -DCMAKE_INSTALL_PREFIX="./.."  \
  ../FreeCAD-git/

Run make

Finally, from a terminal run make to compile and link FreeCAD, and generate the app bundle.

cd ~/FreeCAD/build
make -j5 install

The -j option specifies how many make processes to run at once. One plus the number of CPU cores is usually a good number to use. However, if compiling fails for some reason, it is useful to rerun make without the -j option, so that you can see exactly where the error occurred.

See also Compiling - Speeding up.

If make finishes without any errors, you can now launch FreeCAD by double clicking the executable in the Finder.

Updating from Github

FreeCAD development happens fast; every day or so there are bug fixes or new features. To get the latest changes, use git to update the source directory (see Source code management), then re-run the CMake and make steps above. It is not usually necessary to start with a clean build directory in this case, and subsequent compiles will generally go much faster than the first one.

Building with Qt4

FreeCAD has transitioned from Qt 4 to Qt 5. If you need to build with Qt4, the following additional steps are required.

  1. Append '--with-qt4' to the 'brew install' command.
  2. Do not specify BUILD_QT5 CMake option.
  3. Do not specify CMAKE_PREFIX_PATH CMake option

After you install Qt4, if you want to switch to building with Qt5, you will need to uninstall Qt4.

brew uninstall --ignore-dependencies --force cartr/qt4/shiboken@1.2 cartr/qt4/pyside@1.2 cartr/qt4/pyside-tools@1.2 cartr/qt4/qt

Troubleshooting

Segfault on Qt5 launch

If Qt4 was previously installed via brew, and you then build with Qt5, you may get a EXC_BAD_ACCESS (SEGSEGV) exception when launching the new Qt5 build. The fix for this is to manually uninstall Qt4.

brew uninstall --ignore-dependencies --force cartr/qt4/shiboken@1.2 cartr/qt4/pyside@1.2 cartr/qt4/pyside-tools@1.2 cartr/qt4/qt-legacy-formula

Fortran

"No CMAKE_Fortran_COMPILER could be found." during configuration - Older versions of FreeCAD will need a fortran compiler installed. With Homebrew, do "brew install gcc" and try configuring again, giving cmake the path to Fortran ie -DCMAKE_Fortran_COMPILER=/opt/local/bin/gfortran-mp-4.9 . Or, preferably use a more current version of FreeCAD source!

OpenGL

See OpenGL on MacOS for OpenGL issues when Qt 4.8 and earlier are used on MacOS.

FreeType

When using CMake versions older than 3.1.0, it's necessary to set CMake variable FREETYPE_INCLUDE_DIR_freetype2 manually, eg /usr/local/include/freetype2
