Installing module interafce file

[helynranta]

Hi, I was looking into updating vcpkg port to include module interface file magic_enum.cppm. It seems like cmake install does not copy the cppm file anywhere. My question is, is this correct way to handle this use case? GLM port copies .cppm file with all header files to install folder from which user can add it to CXX_MODULES fileset. Should magic_enum also just copy the module file by default into magic_enum/modules folder (or something similar).

I don't think this is correct, but I will look into it further. Unfortunately, I don’t have much experience working with standard modules yet. Could you advise me on the best way to fix this?

the Ankerl library does it pretty cleanly. i can write pr later today. basically a cmakelist sub-library that links the cppm and then enabled with a -D build flag

edit:
https://github.com/CLIUtils/CLI11/blob/main/CMakeLists.txt is a bit better because it can be used with find_package
