Description:

I am using cmake-gui on Ubuntu to compile programs.

I often encountered warning messages for developpers ending by:

This warning is for project developers.  Use -Wno-dev to suppress it.

I tried to insert this -Wno-dev flag in the CMAKE_CXX_FLAGS box but it doesn't suppress the warnings.

Questions:

I have now two very simple questions:
1) Where exactly should I insert this flag?
2) How to separate it from other existing flags (if any) ?

Probably does not solve your problem with the gui but adding the -Wno-dev from command line works. The flag does not belong to the CMAKE_CXX_FLAGS that are specific for compiler not for CMAKE.

Instead you can suppress the message setting the cmake_policy
