@maxGimeno I think this PR can be tested now. Thanks!

There are warnings in the testsuite. I already fixed the case issue in the cmake script (did it in the doc yesterday but did not think about cmake :( )

Actually, this error is super weird. I already fixed that many times and after pushing it gets back. Maybe it is my editor. I have no idea why this happens((

@sloriot In the last test suite lc-31, there are no errors, and the ones, you refer, do not seem to be caused by the BC package imho. Are they?

[sloriot]

Ic-31 = master

@sloriot I think now it can be tested again. Thanks!
