Thanks for all the comments and help.
I have added the patch to the January CF.
It looks like meson does not currently support building for android, the
following output is what I get (but I have actually no experience with
meson):
meson.build:320:2: ERROR: Problem encountered: unknown host system:
android
Please find an attached patch which also includes a documentation section.
I am happy to adjust if needed.
Kind regards
Matthias
