Translations:Compile on Cygwin/7/en

As far as I know, except of Coin3D and SoQt all libraries are available as prebuilt binary packages from one of the Cygwin mirrors. To install them, first download the latest version of setup.exe from www.cygwin.com and run it with administrator rights. Then follow the instructions of the wizard until the list of all available packages appears. Select the devel files of all the required libraries and install them.
