@delcypher  I am having a problem with my internal build after this change have gone in.  Can you please help to determine what went wrong?  Previously I was able to do the following:

  $ cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=On '-DLLVM_ENABLE_PROJECTS=clang;llvm;compiler-rt;clang-tools-extra;openmp;lld' -DCMAKE_C_COMPILER=/home/llvm/gcc/7.3.0/bin/gcc -DCMAKE_CXX_COMPILER=/home/llvm/gcc/7.3.0/bin/g++ -DLLVM_BINUTILS_INCDIR=/usr/include $LLVM_SRC
  $ ninja -j 20
  $ ninja check-libomptarget check-openmp

After your patch, I get the following warning with the the cmake cmd:

  CMake Warning:
    Manually-specified variables were not used by the project:
      LIBOMPTARGET_NVPTX_COMPUTE_CAPABILITIES
      LIBOMPTARGET_NVPTX_ENABLE_BCLIB
      OPENMP_ENABLE_LIBOMPTARGET

and:

  $ ninja check-libomptarget check-openmp
  ninja: error: unknown target 'check-libomptarget
