[libb2] Build error on arm64-osx (pkg-config issue)

[mntt-SSE]

Hi!

I'm trying to build libb2 on MacOS (arm64-osx), but I get the following error:

-- Fixing pkgconfig file: /Users/Shared/jenkins/vcpkg_/d82f6a36/packages/libb2_arm64-osx/usr/local/lib/pkgconfig/libb2.pc
CMake Error at scripts/cmake/vcpkg_fixup_pkgconfig.cmake:134 (message):
  /opt/homebrew/bin/pkg-config --exists libb2 failed with error code: 1

      ENV{PKG_CONFIG_PATH}: "/Users/Shared/jenkins/vcpkg_/d82f6a36/packages/libb2_arm64-osx/lib/pkgconfig:/Users/Shared/jenkins/vcpkg_/d82f6a36/packages/libb2_arm64-osx/share/pkgconfig:/usr/local/var/jenkins/workspace/build/vcpkg_installed/arm64-osx/lib/pkgconfig:/usr/local/var/jenkins/workspace/build/vcpkg_installed/arm64-osx/share/pkgconfig"
      output: Package libb2 was not found in the pkg-config search path.

  Perhaps you should add the directory containing `libb2.pc'

  to the PKG_CONFIG_PATH environment variable

  Package 'libb2' not found

  scripts/ports.cmake:206 (include)

I've run the following command to install the relevant tools:

brew install autoconf autoconf-archive automake libtool

Any idea what could be wrong or what I can do to debug this further?

Not sure if this is the proper solution or if it works for all platforms, but I was able to get it working on MacOS by adding prefixes to the vcpkg_make_configure() call in the portfile:

vcpkg_from_github(
