Hello, I'm writing a C++11 project. To enable C++11 it requires some switches, such as -std=c++11.
So for the moment, I have in my CMakeLists.txt: set(CMAKE_CXX_FLAGS "-std=c++11") So with that, I'm sure that any build configuration will add this. However, with clang++, you need to pass an additional flag (for FreeBSD especially): -stdlib=libc++. So I would like to be able to do at command line: cmake .. -DCMAKE_CXX_FLAGS="-std=c++11 -stdlib=libc++" But with that, it just ignore my setting and take the one from the CMakeLists.txt What is the correct way to: * Set CXX flags globally, for any type of configuration * Let them be overriden?
