[llvm-dev] add_library cannot create target "LLVMTarget" because an imported target with the same name already exists.

sorry I was just using a dummy name for the library but that wasn’t the name that was giving me the error.
However, what I am experiencing is that if I build and install my pass within the LLVM source I cannot install my library if I build it out-of-tree as a standalone library.
The OpenMP runtime allows that though, any solution?

> LLVMTarget is a library provided by LLVM, you shouldn't be naming your own targets to conflict with the names already in LLVM. CMake does not allow multiple targets to have the same name because it causes ambiguities in the build system.
