[CMake] Specifying compilers?

[Júlio Hoffimann]

I'm very new to CMake, but we can see the C++11 flags are not showing up in
your VERBOSE output.

The way i'm adding flags is by using:

add_definitions(-Wall -Wextra -std=c++0x -pedantic)

Don't know if is the more appropriate CMake command though.

Regards,
Júlio.
