Translations:Compile on Linux/271/en

Support for Python 2 and Qt4 has been removed in FreeCAD 0.20 and it is not necessary to explicitly enable Qt5 and Python 3 if compiling the latest versions. Qt6 support is currently in development and does not work yet. Unless you plan on assisting with the Qt6 migration effort, FREECAD_QT_VERSION should be left at "Auto" (the default) or explicitly set to "5".
