tools/check_build_options/check_build_options.py takes the compile
definitions of the CMake target as the reference and checks that the
CMake pkg-config block, meson_options.txt (name and default), meson.build,
and the Meson section of the package manager docs have each option with
the same definition and condition. It runs as make check_build_options
in the ci_meson_install job, so a new CMake option cannot be forgotten
in the Meson build again.
