[freetype] (Linux) Wrong INTERFACE_LINK_LIBRARIES in config

[Neumann-A]

set_target_properties(freetype PROPERTIES
  INTERFACE_INCLUDE_DIRECTORIES "${_IMPORT_PREFIX}/include;${_IMPORT_PREFIX}/include/freetype"

)

entry: /mnt/d/xlinux/installed/x64-linux/debug/lib/libz.a missing generator expression for debug/release. Links only debug

I have a bad hunch: Is this issue a common issue?

This issue is because the final target when looking for zlib is not optimized;xx;debug;xx type.

[Neumann-A]

Yeah that is a common issue if you do not use targets but link libraries directly in VCPKG.
This also happens if the variable used does not have the optimized/debug keywords. In general it would require a vcpkg-cmake-wrapper.cmake for the upstream port (zlib) to correctly fix the <var>_LIBRARIES.
Such issues could be automatically detected as mentioned in #12215 (last comment paragraph in the changeset)

[JackBoosY]

@Neumann-A So I assume your PR can fix this issue, right?

[Neumann-A]

@JackBoosY: which one? #12215? No that one adds only and option to deactivate the prefix correction nothing more.
