I don't know why but Windows CI doesn't work, I've installed pkg-config and it works and the two packages. I set up the environment variable but without any result. Do you know what could be the problem?

vcpkg build packages from source code, so it will take a lot of time rather than apt in ubuntu. By default, vcpkg build both debug and release version. You can disable debug version by add set(VCPKG_BUILD_TYPE release) to triplets/x64-windows.cmake , that would save time.

Thank you for the advice! I'm going to add that later, but for now the problem is that I can't build the code. It seems there is an hindrance here

I noticed CI log. There is a bug in vcpkg that the version info in opus.pc is "0". You may modify yourself, it's 1.3.1, I guess.

How can I do that?

[asuper0]

the file vcpkg\installed\x64-windows\lib\pkgconfig\opus.pc . It looks like

prefix=${pcfiledir}/../..
# Opus codec reference implementation pkg-config file

exec_prefix=${prefix}
libdir=${prefix}/lib
includedir=${prefix}/include

Name: Opus
Description: Opus IETF audio codec ( build)
URL: https://opus-codec.org/
Version: 0
Requires:
Conflicts:
Libs: -L"${prefix}/lib" -lopus
Libs.private: 
Cflags: -I"${prefix}/include/opus"

Change Version: 0 to Version: 1.3.1 or Version: 1.3.1-34-g5c94ec32

Here is the issue and they fixed it but not merge yet.

Yeah, it works now! Unfortunately, I wasn't able to shatter down libvpx building time even though it seems we are in Release mode

[asuper0]

I find out that is because the config in libvpx. It is set to not build debug by default.
BTW, the PR in vcpkg is merged today.

So can I remove the set(VCPKG_BUILD_TYPE release) part?

Perfect, let me see if I can remove the hack step from CI

No, that can save time while building opus and other packages in the future. I advise to keep it.

@asuper0

Thank you for your review! I should have solved and clarified everything, as soon as you approve this PR I'm going to merge it.

[asuper0]

That's good!
