Hi! I order to solve the warning “clang version too old to be used with SSCP compiler , diabling WITH\_SSCP\_COMPILER” i used several comands such as:
-DLLVM\_DIR=/path/to/llvm/cmake
-DCLANG\_EXECUTABLE\_PATH=/path/to/clang++
-DCLANG\_INCLUDE\_PATH=/path/to/clang-includes
But no one is solving this problem, i still build with old compilator in /usr/lib/llvm-11/cmake
What should i do?

Actually, i resolve this by simple deleting older versions. However if you have less hardcore methods, i open to listen!

This doesn’t seem like the right place; whatever project wants this SSCP compiler is likely what needs to consider ignoring older versions.
