Not compatible with new SVF versions.

[learjet5]

When I'm using LLVM-14.0.6 and SVF-2.8, I can't cmake SVF-example.

The output error is that:

-- Failed to find installed SVF instance; using legacy import method
CMake Error at CMakeLists.txt:158 (message):
  SVF & LLVM RTTI support mismatch (SVF: , LLVM: OFF)!
