@twslankard Hi, could you review this patch?

I agree with @tokoro10g, the CMAKE_CXX_COMPILER_LAUNCHER was introduced in CMake 3.4. so 3.10 should be covered.

@Samahu
I updated the description of this PR to meet the requirements on CI. Could you rerun the check?

@tokoro10g unfortunately GH or the script that checks PR description does not pick the changes, but nonetheless I went ahead and merged your proposed fix. Thanks for your contribution!
