[package] xkbcommon/1.5.0: build fails on Linux if build triggered from build context (conan bug with <host_version>?)

Description

xkbcommon/1.5.0 build fails on Linux:

Run-time dependency wayland-client found: NO (tried pkgconfig and cmake)
Found pkg-config: /home/spaceim/.conan2/p/b/pkgco720a404f4464b/p/bin/pkgconf (2.0.3)
Build-time dependency wayland-protocols_build found: YES 1.31
Build-time dependency wayland-scanner_build found: YES 1.22.0

../src/meson.build:481:12: ERROR: Problem encountered: The Wayland xkbcli programs require wayland-client >= 1.2.0, wayland-protocols >= 1.7 which were not found.
You can disable the Wayland xkbcli programs with -Denable-wayland=false.

os=Linux
arch=x86_64
compiler=gcc
compiler.version=12
compiler.libcxx=libstdc++11

Steps to reproduce

Hard to reproduce, you have to put xkbcommon somewhere in a build context dependency graph (for example qt as a tool_requires will lead to a build of xkbcommon in build context).

Can you please provide /home/spaceim/.conan2/p/b/xkbco9f60d54155a8e/b/build-release/meson-logs/meson-log.txt ?

[bukulin]

I faced the same issue but only if host and build profiles differ.

Corresponding meson log attached.
meson-log.txt

Relevant parts from the aforementioned log file shows, that expat_BUILD.pc and libxml-2.0_BUILD.pc files were missing from the PKG_CONFIG_PATH aka build/conan directory, and that is true:

 ~ $ ls -1 /home/nbukuli/.conan2/p/b/xkbco68fa6088ec723/b/build-debug/conan/*_BUILD.pc
/home/nbukuli/.conan2/p/b/xkbco68fa6088ec723/b/build-debug/conan/wayland_BUILD.pc
/home/nbukuli/.conan2/p/b/xkbco68fa6088ec723/b/build-debug/conan/wayland-client_BUILD.pc
/home/nbukuli/.conan2/p/b/xkbco68fa6088ec723/b/build-debug/conan/wayland-cursor_BUILD.pc
/home/nbukuli/.conan2/p/b/xkbco68fa6088ec723/b/build-debug/conan/wayland-egl-backend_BUILD.pc
/home/nbukuli/.conan2/p/b/xkbco68fa6088ec723/b/build-debug/conan/wayland-egl_BUILD.pc
/home/nbukuli/.conan2/p/b/xkbco68fa6088ec723/b/build-debug/conan/wayland-scanner_BUILD.pc
/home/nbukuli/.conan2/p/b/xkbco68fa6088ec723/b/build-debug/conan/wayland-server_BUILD.pc
~ $ 

If build and host profiles do not differ, so only -pr is given rather than -pr:h, -pr:b for conan install then the build succeeds.

I have a fix available for this in my private fork:
https://github.com/valgur/conan-center-index/blob/67918ce424b0aa27b04b50c6eecd115faa2f575d/recipes/xkbcommon/all/conanfile.py#L112-L117

The same issue is present in all other Meson projects using Wayland as well.

@valgur great, thank you!
