colcon-pkg-config

colcon-pkg-config is a colcon extension that provides an environment hook to correctly set the `PKG_CONFIG_PATH` during `colcon build` operations. It ensures that `share/pkgconfig` directories of previously installed packages within the workspace are added to `PKG_CONFIG_PATH`, making `pkg-config` files discoverable for subsequent builds. The current version is 0.1.0, and its release cadence is infrequent, typically aligning with colcon core developments or specific ROS releases.
