Pull in some code from CMake 3.12.4's FindPkgConfig.cmake to arrange that, when running pkg-config, directories from CMAKE_PREFIX_PATH are in the PKG_CONFIG_PATH environment variable. We do this because we want to make sure that, if CMAKE_PREFIX_PATH is set, and it points to a directory that contains a libpcap that has a .pc file installed, we get that .pc file, but we don't yet want to require a minimum of CMake 3.1 or later (CMake 3.1 and later do that automatically) because there might be some long-term support OS version that comes with an older version of CMake. |
