"Build Project" is grayed out & "Setting->CMake->Build directory" doesn't work as expected

Hello!

Please do `Tools | CMake | Reset Cache and Reload Project` and show the entire output from the CMake tool window.

Hi, I think it works after going for Tools|CMake|Reset Cache and Reload Project. Now I can change the build directory. However the Build | Build Project is still grayed out. Any ideas? Thanks

Below is the CMake output:

OpenGL_GL_PREFERENCE has not been set to "GLVND" or "LEGACY", so for
