This depends on how the compiler is installed. There are several installers that do not put the libraries in `/usr/lib`. BTW, that directory doesn't exist by default anymore on macOS, even if Xcode and the command line tools are installed.
My bad. "/usr/lib" exists, it's "/usr/include" that usually doesn't exist. -- /Jacob Carlborg
