[bug] PkgConfig not using buildenv?

[jasal82]

Environment details

• Conan version: 1.61.0

Steps to reproduce

When I use PkgConfig in a recipe which has a Yocto toolchain package in its build requirements the environment variables set by this package via buildenv_info are not visible to PkgConfig. However, when I set the same variables with env_info it works fine. I think this is not the intended behavior. Yocto toolchains set PKG_CONFIG_PATH so that the pkg-config executable can find the correct .pc files. Without this variable it will query the host system instead.

But it could also be that I am simply using it incorrectly. What is the intended pattern for passing environment variables like CC, CXX, CFLAGS and so on from a build_requires to other recipes in the dependency graph? Following the naming scheme I would have thought that buildenv_info is the correct one, but the current documentation is a bit thin.

Sorry this was not responded back then.

There is a more thorough discussion about this in #14422, and the solution is being documented in conan-io/docs#3811. I think this ticket can be closed, and we can follow up in those other ones, thanks!
