Compilation without python bindings

With the latest commits it is not possibile to compile without python bindings,
but the it should be as stated in the CMake options, using USE_PYTHON=OFF.

thanks for the report - Netgen+NGSolve will work without Python again very soon

It’s fixed on master now (there were issues with Netgen and NGSolve).

Thank you. Now it compiles.
There is only one thing though: I had to force the exclusion of OpenCascade support with the instruction -DUSE_OCC=OFF, but according to this document cmake options it should be the default.
