Re: Help with CMake linking Debian's LLVM libs
Hi Gianfranco,
thanks for the quick reply.

Good question. They didn't include a complete checkout but only a subset
of files, now of which contains a version number. I can try to match
md5sums of their bundled files against the various releases to try and
find a mapping that uniquely identifies a version...

Yes, I suspected that as well and tried LLVM toolchain versions 3.6 and
3.7, both came up with the same error as mentioned in the original mail.
3.8 and 3.9 seem to lack the necessary CMake plugins in the first place
so I can't even try:
[...]

This is apparently a known problem, see also:
