I have tried setting the debug flags using the
set command in cmake but I cam unsure what to add. I have been told things like DEBUG=true but so far i am unable to find the correct flag to set.

How to enable debugging with cmake? If we use cmake to build the project, we may want to enabling the debuging mode that cmake invoke gcc with the -g so that we can debug the compiled program with gdb. This can be enabled by adding the CMAKE_BUILD_TYPE parameter to cmake: cmake -DCMAKE_BUILD_TYPE=Debug .
We can use CMAKE_BUILD_TYPE to set the configuration type: cd debug cmake -DCMAKE_BUILD_TYPE=Debug .. cmake --build . cd ../release cmake -DCMAKE_BUILD_TYPE=Release ..
If you want to build for debug (including source information, i.e. -g) when compiling, use
cmake -DCMAKE_BUILD_TYPE=Debug <path> If you want to build a release build, you can use
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo <path> Alternatively you can use the CMAKE GUI to make this change. Doing ccmake with the project will yield a screen similar to this:
Entering Debug in the CMAKE_BUILD_TYPE field will allow you to build with debug flags.
