CMake deprecation warning

[N4gtan]

Describe the bug
This currently isn't an issue but CMake recently started throwing a deprecation warning

CMake Deprecation Warning at ghc/CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.10 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

To Reproduce
Configure with CMake.
