This came up on the CMake discussion forum. I'm trying to get my project working with C++20 modules, and I noticed everything recompiling when I changed something in the private module segment (ie, after `module :private`)
https://discourse.cmake.org/t/c-20-modules-update/7330/41
I'm not 100% sure myself whether Clang should do this, but it seems like it should. It seems like the compiler is in a better position to do this than the build tool. (?)
