I'd guess cmake failing to find pthread is local to your system.

Target offloading can't build with GCC. It will build with any recent clang but the result won't necessarily work for offloading unless the library is from the same checkout as clang.

The offload libs should default to build under enable_runtimes (as they'll work) and to not build under enable_projects. That needs a fix to the cmake to detect which is happening.
