You can copy out the numpy/core/lib/npy-pkg-config directory, add a
        pkgdir value to the .ini files and set NPY_PKG_CONFIG_PATH environment
        variable to point to the directory with the modified npy-pkg-config
        files.

            prefix=${pkgdir}
            libdir=${prefix}/lib
            includedir=${prefix}/include
