CMake build types

CMakes features various predefined build types depending on the language and the implementation.
They can be set through the CMAKE_BUILD_TYPE special variable.
Unfortunately, they are poorly documented.
On Ubuntu 16.04, looking at /usr/share/cmake-3.5/Modules/Compiler/GNU.cmake brings some insights.
In C, there are five: None (empty string), Release, Debug, MinSizeRel and RelWithDebInfo.
For GCC, it translates into the following command-line flags:
- Release:
-O3 -DNDEBUG - Debug:
-g - MinSizeRel:
-Os -DNDEBUG - RelWithDebInfo:
-O2 -g -DNDEBUG
However, in SaBRe, the flags for Debug are overridden to be -ggdb3 in loader/CMakeLists.txt.
