[PATCH] D93794: Fixed a build error when using CMake 3.15.1 + NDK-R20

[AnZhong Huang via Phabricator via llvm-commits]

azhuang added a comment.

  using BenchType =
      internal::LambdaBenchmark<typename std::decay<Lambda>::type>;

should be correct, I didn't see the original change, but my patch just passed the build, so I thought it's a correct fix.

The build error message without the patch.
