# libomptarget makes use of multithreading via the standard C++ library (e.g.
# std::call_once), which, depending on the platform and the implementation of the standard
# library, might or might not require linking to libpthread (note that the failure might
# happen at the linking time as well as at the runtime). In some cases, the required linker
# flag comes as a transitive dependency (e.g. from the static LLVMSupport component). The
# following patches enforce linking to the thread library that is relevant for the system,
# which might lead to overlinking in some cases though.
# TODO: figure out why we do not use LLVM_PTHREAD_LIB but run find_package(Threads), at
# least for newer versions (the solution must work with both openmp=runtime and
# openmp=project)
