Describe the bug
Hi! Let me start of by saying thanks for your great work with conan.
My current goal is to setup a hello-world qt project for arm64v8.
The OS-Team gave me a nice toolchain to compile for the arm64v8 platform.
BuildOS: ubuntu24.04
conan-version: 2.15.0
How to reproduce it
I got the following conanfile.py created by conan new cmake_exe -d name=foo -d version=1.0
from conan import ConanFile
from conan.tools.cmake import CMakeToolchain, CMake, cmake_layout, CMakeDeps
class fooRecipe(ConanFile):
name = "foo"
version = "1.0"
package_type = "application"
# Optional metadata
license = "<Put the package license here>"
author = "<Put your name here> <And your email here>"
url = "<Package recipe repository url here, for issues about the package>"
description = "<Description of foo package here>"
topics = ("<Put some tag here>", "<here>", "<and here>")

settings = "os", "compiler", "build_type", "arch"

ConanException: PkgConfig failed. Command: /mnt/work/Development/conan-fun/toolchain/sysroots/x86_64-pokysdk-linux/usr/bin/pkg-config --print-provides

stdout:
stderr:
Package gl was not found in the pkg-config search path.
Perhaps you should add the directory containing `gl.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gl' found
The thing is, that /mnt/work/Development/conan-fun/toolchain/sysroots/armv8a-poky-linux/usr/lib/pkgconfig contains the gl.pc.
I can verify it by using all the values from the conan logs:
export PKG_CONFIG_PATH="${PKG_CONFIG_PATH}:/mnt/work/Development/conan-fun/toolchain/sysroots/armv8a-poky-linux/usr/lib/pkgconfig"
export PKG_CONFIG_PATH="${PKG_CONFIG_PATH}:/mnt/work/Development/conan-fun/toolchain/sysroots/armv8a-poky-linux/usr/share/pkgconfig"
/mnt/work/Development/conan-fun/toolchain/sysroots/x86_64-pokysdk-linux/usr/bin/pkg-config --print-provides gl --print-errorsgives gl = 1.2. Without the environment variables PKG_CONFIG_PATH I get the same error like conan.
So I assume there is an issue with conan in package_info not setting the environment variables given by the [buildenv] profile.
The PKG_CONFIG_PATH works nicely in other contexts with conan.
What do you think?
Thanks for your time! :)
Cheers
