Note that theres nothing QtCreator spesific here (debug options apply
to any CMake build).

In your build directory run cmake-gui (or load CMakeCache.txt in an editor).

CMAKE_BUILD_TYPE should be set to Debug, so you should have this text.

CMAKE_C_FLAGS_DEBUG should contain "-g/-g3/-ggdb3"
CMAKE_C_FLAGS_DEBUG:STRING=-ggdb3 -fno-inline -O0 -Wall

Then you'll get debug symbols.

You would have to link to a full error log of the output, otherwise
its hard to know whats going wrong.
