Ubuntu: Could not find a configuration file for package "LLVM" #25
Description
Recently I've started seeing this in my CI jobs on Ubuntu Bionic:
Could not find a configuration file for package "LLVM" that is compatible
with requested version "11.0.0"
It turns out that the package for LLVM 11 for Ubuntu Bionic started claiming to be version 11.1.0 rather than 11.0.1 or 11.0.0.
As LLVM 11.1.0 has not been released yet (rc1 has just been tagged: llvm-dev thread), I assume that this is a bug in the packaging. I reported it here.
Although LLVM 11.1.0 and LLVM 11.0.0 will be ABI incompatible, I doubt that this will affect llvm-tutor. But it does confuse the CMake scripts.
