The file is then included in `TargetParser.cpp` but also in `TargetParser.h` -> this means that every time we include the latter in a cpp file we need to make the inc file visible for inclusion.

I think, if that is the case, we should add `{make_build_folder}/lib/TargetParser` as a public include directory of the LLVMTargetParser library, which should mean anything depending on it gets that as an include directory they can rely on.
