* coin3d 4.0.0 default location is /usr/share/doc/Coin/html/
* misuses of find_files() if several candidates for filename
* export variable COIN3D_DOC_FOUND that is used by cMake/FreeCAD_Helpers/PrintFinalReport.cmake
Found that on ubuntu 20.04 where QT is still at 5.12, these are called pyuic5 and pyrcc5 now and cmake will not find these and then the build fails without this change
Since PySide2 5.14, 'pyside2-rcc' and 'pyside2-uic' have been renamed into plain 'rcc' and 'uic'.
This leads FindPySide2Tools.cmake to no longer find rcc/uic, as reported in bug #4229 (https://www.freecadweb.org/tracker/view.php?id=4229) and prevents compilation.
FindPySide2Tools has been updated accordingly.
If INSTALL_TO_SITEPACKAGES is enabled, the freecad-namespace package (freecad/__init__.py) is installed in the python-sitepackage-dir. Further, the library install path (CMAKE_INSTALL_LIBDIR)
is used to find the FreeCAD shared library. If, for some reason, one wants to import another installed FreeCAD version it's possible to set the environment variable "PATH_TO_FREECAD_LIBDIR" to
point to the wanted FreeCAD-library (FreeCAD.so / FreeCAD.dll)
Windows- copy plugins/styles and plugins/printsupport to bin
copy libpack/bin/QtWebEngineProcess.exe and libpack/bin/qt.conf to build/bin
copy assistant.exe to build/bin
Do not overwrite NETGEN_VERSION that might be cached. Use a new variable instead, NETGEN_VERSION_C.
Use cmake internal system to specify std=c++14, else you can end up with `c++ -DFOO -std=c++14 -Ibar -std=c++11`, and the latter is used.
Netgen provided cmake file, and the internal detection, had different casing
for the _FOUND variable
When detecting the Netgen include-directories, we only want the /include in
addition to the global one. To include a given header file, specify which
part of the library, or use the one from the project/include directory.
libmedc is built with openMPI, while freeCAD selects hdf5-serial.
libmed declares functions prototypes which has MPI parameters if
built for openMPI, causing compilation errors. Doing some online
searches reveals that some users manually changes the include-paths
to hdf5-openmpi if this error happens.
This patch tries to autodetect this situation.
