find_library: 3.25.0 finds GNU-ABI libfoo.a libraries when targeting MSVC ABI

Original Subject: include files mixed between msys64/mingw64 and VS 2019 with latest cmake-3.25.0 when building drogon C++ http server

Hi! I'm getting weird compile errors when building https://github.com/drogonframework/drogon (cloned from git) with latest cmake-3.25.0.

Platform : Windows 10

Build env :

• compiler: VS 2019
• shell: ConEmu + msys64 bash.exe
• mingw64 gcc is also installed on this dev box, but it should not be used in this project. cmake correctly detects VS 2019 (i.e. dump it in standard output), chooses the VS build chain and generates .sln/.vcxproj files for VS.

The project always builded fine fo months, until I upgraded cmake from 3.24.3 to to 3.25.0 yesterday.

Now when compiling the "drogon" project (drogon solution has many projects), I get mixed include files from VS2019 and mingw64 in the compiler output ! e.g. :

• Of course I removed CMakeCache.txt and relaunched cmake to reconfigur the VS solution after upgrading to 3.25.0.

• Above log is from within VS 2019 (Build Solution) but I'm getting the same errors when building in bash + cmake command "cmake --build ~/path/to/git/drogon --config Release".

• If I revert to 3.24.3 everything build fine again (so I reverted for now).

Not sure what's going on here.
