Cpplint and CMake - Treat warnings are errors and fail

Question

I'm using cpplint with CMake:

set(CMAKE_CXX_CPPLINT cpplint;
    --filter=-build/include_subdir,-legal/copyright;
    --quiet)

But even if cpplint produces some warnings, the build is still successful.
I cannot find a way to treat those warnings as error (similarly to when using -warnings-as-errors for clang-tidy) and fail the build instead.

Answer 1

CMake always ignores the cpplint exit code.
