How can I add a minimum compiler version requisite?

Question

I want to create a project in C++11 and I use CMake as my build system.

How can I add a minimum compiler version requisite in the CMake config files?

Answer 1

You can check the specific gcc version as follows:

if (CMAKE_COMPILER_IS_GNUCC AND CMAKE_CXX_COMPILER_VERSION VERSION_LESS 5.1)
    message(FATAL_ERROR "Require at least gcc-5.1")
endif()
