- We need to confirm compiler support for module scanning before
creating the CXX_MODULE FILE_SET using the `target_sources` command
- This is especially relevant for compilers that have module support but
do not support the module scanning such as g++13, clang15. For these
we can use the older way of creating the fmt-module target
