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

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.
