I see the following messages raised when include-what-you-use is running during cmake build:

warning: optimization flag '-fno-fat-lto-objects' is not supported
error: unknown warning option '-Wduplicated-cond' [-Werror,-Wunknown-warning-option]
error: unknown warning option '-Wduplicated-branches' [-Werror,-Wunknown-warning-option]
error: unknown warning option '-Wlogical-op'; did you mean '-Wlong-long'? [-Werror,-Wunknown-warning-option]
error: unknown warning option '-Wuseless-cast' [-Werror,-Wunknown-warning-option]

These warnings are set by CompilerWarnings.cmake.
