clang-cl will pick up command-line options from the CL and _CL_
environment variables similarly to MSVC (see
https://docs.microsoft.com/en-us/cpp/build/reference/cl-environment-variables?view=msvc-160)

But if you set CL=/showFilenames and then use MSVC instead of
clang-cl, it will warn about the unknown flag. So it's not a perfect
solution.
