GCC supports naming the output file by asking the "module mapper" where a module with a given name lives (also used for finding imported modules). MSVC uses the `-ifcOutput` flag to specify where to write any exported module data to. See this CMake code which handles the "module mapping" for the various compilers: https://gitlab.kitware.com/cmake/cmake/-/blob/master/Source/cmCxxModuleMapper.cxx
