[SOLVED] OpenGL Error when Compiling SOFA on MacOS

Dear community,

when trying to compile SOFA on my Mac, I get this error:

[ 16%] Building CXX object SofaKernel/SofaFramework/SofaHelper/CMakeFiles/SofaHelper.dir/src/sofa/helper/gl/FrameBufferObject.cpp.o
make[2]: *** No rule to make target <code>/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/System/Library/Frameworks/OpenGL.framework', needed by</code>lib/libSofaHelper.20.06.00.dylib'.  Stop.
make[2]: *** Waiting for unfinished jobs....
make[1]: *** [SofaKernel/SofaFramework/SofaHelper/CMakeFiles/SofaHelper.dir/all] Error 2
make: *** [all] Error 2

I followed the steps exactly as described in the documentation and tried different versions of SOFA, including v19.12, v20.06, and v20.12, but I always get stuck during the compilation with the same error. When activating SOFA_NO_OPENGL in CMake, everything works fine but since I want to use the CGAL plugin, I need OpenGL. However, the path to the OpenGl framework seems to have been moved to
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks
wherefore it cannot be found on the path mentioned in the error message.
I already tried updating (and reinstalling) XCode as proposed here, xcode-select -p also looks fine. I also upgraded glew and checked my compilers, as mentioned here. None of these solved the problem.

My macOS version is macOS 10.15.7, I’m using Apple clang version 12.0.0 (clang-1200.0.32.29) and XCode Version 12.4.

I will be grateful for any help!

Best
