cmake_minimum_required version is incompatible with CMake 4 and higher

I'm trying to build libxc@7.0.0 via Spack using cmake@master. I'm using cmake@master to test the new support for Nvidia Performance Libraries (NVPL).

I run into the following issue when building libxc@7.0.0:

  >> 15    CMake Error at CMakeLists.txt:10 (cmake_minimum_required):
     16      Compatibility with CMake < 3.5 has been removed from CMake.
     17    
     18      Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
     19      to tell CMake that the project requires at least <min> but has been updated
     20      to work with policies introduced by <max> or earlier.

CMake 4.0 removed compatibility with CMake <3.5, therefore the build fails because libxc uses 3.1 as minimum version.
