I need working pkg-config with my own list of folders for ARM cross development. I installed it via HomeBrew, changed the PKG_CONFIG_PATH but it seems pkg-config does not use the PKG_CONFIG_PATH environment variable at all. Maybe I'm misunderstanding something, or doing something wrong? How I can make pkg-config look into my selected folders?
[mars@mbp]:~/develop/rp3> echo $PKG_CONFIG_PATH
[mars@mbp]:~/develop/rp3> pkg-config --variable pc_path pkg-config
