Answer 1

CMake does not currently support C++20 modules like the others have stated. However, module support for Fortran is very similar, and perhaps this could be easily changed to support modules in C++20.

Now, perhaps there i an easy way to modify this to support C++20 directly. Not sure. It is worth exploring and doing a pull request should you resolve it.
