Setting QtCreator compiler build flags when using cmake, gcc on linux -std=c++14

This question is asked many times on stackoverflow but there no good and specific answers that I can find there or here. Can't find any reference in the Qt manuals either. Where exactly should I look in the documentation it it exists?
Presuming there is no documentation :(, here is what I've done:
Built a 'non-Qt project/plain c++ application' project using CMake with a custom 'kit' using QtCreator.
The custom kit consists of a 'Desktop Qt 5.5.1 GCC 64bit2' with a custom compiler.
The custom compiler consists of a 'clone' of the auto-detected GCC X86 64bit and invokes /usr/bin/g++ using an x86-linux-generic-elf-64bit ABI. I get a compiler error when I build from the IDE saying that some of my code is not supported in c++98. I can build and run using old syntax, but when I use c++14 syntax, I get compiler errors due to the lack of the -std=c++14 flag on the gcc (5.3.1) invocation.
In hopes of making it work I put "-std=c++14" in the 'Platform codegen flags' text box. It appears to have no effect.
Thanks in advance for any help.
Hi and welcome to devnet,
Just to be sure are you using CMake or qmake for handle your project ?
If CMake then this page might be of use.
Hope it helps
