Answer 1

The cause of this issue is a bug in CMake -- it does not use alternate pkg-config paths correctly.

According to the merge request attached to the bug, the fix should be in cmake 3.17.0 (to be released in Feb 2020).

Otherwise, use this work-around. Hard coding it in your CMakeLists.txt will make things bad for people who use MacPorts instead of Homebrew.
