[CMake] CXX_CLANG_TIDY doesn't handle multiple arguments correctly

[Tiago Macarios]

This works for me:

    CXX_CLANG_TIDY
        "/usr/bin/clang-tidy"
        "-checks=modernize-*,readability-*,performance-*"
        "-fix"

I think the difference are the semicolons in the checks instead of commas.
