Changing CMAKE_CXX_FLAGS in project

Question

I have the following content in my CMakeLists.txt:

project( Matfile )

SET ( CMAKE_CXX_FLAGS \"-std=c++0x\" )

set ( SOURCES
      \"foo.cpp\"
      \"bar.cp         


        

Answer 1

This is the solution I currently use:

if(CMAKE_COMPILER_IS_GNUCXX)
    add_definitions(-std=c++0x)
    add_definitions(-std=gnu++11)
endif()

Or, if you have an older version of cmake and you want to see it show up in cmake-gui:

set_property(CACHE CMAKE_CXX_FLAGS PROPERTY VALUE "-std=c++0x")
