CryptoPP 8.9.0 fails to link when using MSYS2 Clang

I see the same on the CI builds. I don't have the environment for testing this myself. Could you please build crypto++ manually using its Makefile and check if it's working?

I know the preprocessor logic has changed specifically for clang in 8.9.0 in crypto++ (not ceyptopp-cmake). But we don't see any issue on Linux or Mac clang builds.

We'll leave it open until weidai11/cryptopp#1241 is solved. Sometimes there are side effects of fixes in crypto++ that require changes to cmake files...

This is now fixed in the master branch of cryptopp-cmake. However, because cryptopp-cmake tracks the released version of crypto, it will not be reflected in the build unless you are building with the master branch of crypto using the CRYPTOPP_SOURCES make variable.

Once cryptopp version is released with the fixes made there, this project will release a new tracking version as well.
