I tried to statically compile LLVM, but encountered some issues.

May I ask what is the solution?

    -DLLVM_TOOL_LLVM_DEBUGINFOD_FIND_BUILD=OFF

For static builds and especially LTO static builds, some llvm-tools usually fail to build or are extremely time-consuming, what I do is to look for their corresponding build options in CMakeCache and turn them off.

I don't understand why or how to do it
