does this mean that multiple shared libs are not supported by mesa? I read
from the llvm website, that

"BUILD_SHARED_LIBS is only recommended for use by LLVM developers. If you
want
to build LLVM as a shared library, you should use the LLVM_BUILD_LLVM_DYLIB
option."

I wonder why mesa tries to gather a list of required libs then (for static
linking maybe?)

Unfortunately, opensuse does not provide static libs....

Will also add this to the bug report.


Static libs might not work very well with Mesa. It's a rarely tested option
and I wouldn't recommend it.
