helloworld.cpp:

    std::cout << "libavif version: " << version << std::endl;

vcpkg.json:

When trying to build in macOS results in the following error: helloworld.cpp:1:10: fatal error: 'avif/avif.h' file not found. I believe the same would happen in Linux, but not Windows (didn't try w/ this minimal project but that's what I was seeing with a much larger project that uses libavif), with the difference presumably being that the library is static in macOS/Linux. If the override in vcpkg.json is set to version 1.0.4#2, it works fine.

Comparing the CMake files in vcpkg_installed/arm64-osx/share/libavif from version 1.0.4#2 to 1.1.1 reveals that the following section disappeared:

set_target_properties(avif PROPERTIES
  INTERFACE_INCLUDE_DIRECTORIES "${_IMPORT_PREFIX}/include"
  INTERFACE_LINK_LIBRARIES "\$<\$<NOT:\$<CONFIG:DEBUG>>:${VCPKG_IMPORT_PREFIX}/lib/libdav1d.a>;\$<\$<CONFIG:DEBUG>:${VCPKG_IMPORT_PREFIX}/debug/lib/libdav1d.a>;\$<LINK_ONLY:yuv>;\$<LINK_ONLY:m>;\$<LINK_ONLY:Threads::Threads>"
