Compile with libraries with MSVC

[dimasafonis]

I can't compile libraries using MSVC 2022.
This line:
./configure --toolchain=msvc
creates libraries in .a format which is incompatible with MSVC.
This line:
./configure --toolchain=msvc --enable-shared
creates normal .lib and .dll files, but I can't use it with pkg-config because pkg-config uses -lm flag but there's no m.lib file in Windows.

Last time msvc worked was in 2021. ​https://github.com/mcmtroffaes/ffmpeg-msvc-build

There were some fixes since then but I dunno whether it works.

And anyway, MSVC produces worse binaries than gcc for windows.

Why? .a file is just a static linked library, called .lib in windows. .dll is on linux .so and is dynamic (well, except for the whole ld-linux.so mess, cause ld-linux.so is an executable really, link to ld-linux.so is absolute in all .so).

Does renaming to .lib work?

Renaming to .lib works. Thank you very much.
I thought it's an ar archive and msvc can't work with it.
Now it works, but why does configure set a static library prefix incorrectly?
And why does it search for the m library on windows? It checks if dlopen and dlsym are in a separate library or not. So why doesn't it do the same with m library?

Does it even support VS 2022?

You mean libm.so? You do understand windows math.h standard library is also called libm, right? ​https://github.com/amd/win-libm/blob/master/pow.asm#L108
