# alpine's gmime+json-glib packages don't have static variants. We'll need
# to compile them ourselves. (Debian doesn't have json-glib, either, and it
# uses glibc, which shouldn't be statically linked.)
#
# Note the icky hack for mesontest. Newer versions of meson use "meson test";
# older ones allowed "mesontest". json-glib still uses "mesontest".
