The {fmt} library for the upcoming C++ 20 standard compiles under MSVC, but not Intel unless /Qipo is switched on

The Intel Compiler v19.0 has a bug where it fails to link in pre-compiled header mode, unless Interprocedural Optimization: Multi-File (/Qipo) is switched on. This bug is not present in MSVC.

If you wish, I can provide a sample project if you cannot reproduce the issue.
