To configure and build:
meson build && meson compile -C build
To specify additional pkgconfig locations:
meson build --pkg-config-path ~/build/meson-glib/lib/pkgconfig/ OR meson build --pkg-config-path ~/src/glib/build/meson-uninstalled
NOTE: This also sets the RPATH appropriately for us.
By default meson produces debug builds. To build for release:
meson build --buildtype release
