Pascal,

For now I've put a couple of commits into master which re-enable BTLS 
for 5.8.022 and 5.4.0.201. Both of these seem to build with your cmake 
dependency added.

After listening to the team at #OEDEM I've been working to add basic 
Image Test support to core-image-mono and to get the Yocto Auto Builder 
going so I can automate some testing of the yocto release vs mono 
version vs mono features matrix

That's finally coming together at which point I'm hoping to genericise a 
bit more.

There are currently just three basic run time tests which previous to 
the image test support I've been performing manually

If you have suggestions/patches for an image test for TLS (or indeed any 
other tests) they'll be gratefully received.

At some point I want to extend this with ptest support for running the 
Mono test suite on the target { qemu / real hardware etc }
