Translations:Compile on MinGW/16/en

Here is a description which libraries we need for FreeCAD and how to build them from the sources. In order not to pollute our MinGW installation with too many files from the 3rd party libraries we have to build you can e.g. create a sub-directory "local" in your MSYS installation. If you have installed MSYS under C:\MSYS then simply create the directory C:\MSYS\1.0\local.
