BABL meson build process does not work when repository is a submodule
If you clone the directory and run meson build
everything works perfectly.
However, if you use git submodule add https://gitlab.gnome.org/GNOME/babl.git
in any repository, cd
into it and then try to run meson build
it will fail, claiming git-version.h
does not exist.
I believe this is a bug with the check that verifies if the code is running inside a git repository. The same seems to also apply to GEGL.
