Right. I forgot that we honor CMAKE_<LANG>_FLAGS for the compiler id: http://www.cmake.org/gitweb?p=cmake.git;a=blob;f=Modules/CMakeDetermineCompilerId.cmake;hb=v3.3.1#l24 That eliminates my concern. The use of multiple flags is not a big problem because the right one wins, and the user did ask for the "loser" to be there even though the project knows how to add the latter. > -std=c++11 -std=gnu++11 > > appears instead, which is consistent with the design of CompileFeatures. > Arguably the -std=gnu++11 should not be added in that case, but changing > that existing behavior would be a different topic. Yes, and it can be done later if found to be necessary.
