How to build pandora for debugging, profiling and release

1. Go to a build folder
2. Build the project accordingly to what you want to do:
   1. For debugging:
      • cmake -DCMAKE_BUILD_TYPE=Debug .. && make -j 4
      • Flags passed to compiler: -g
      • ctest -VV will work here, so you can check if the code is indeed working;
      • If you do not use this to debug, variables will get optimized out and functions will get inlined, making it hard to debug;
   2. For profiling (e.g. callgrind):
      • cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo .. && make -j 4
      • Flags passed to compiler: -O2 -g -DNDEBUG
      • ctest -VV will NOT work here as asserts are turned off;
   3. For release (or if you want to test the most optimized executable):
      • cmake -DCMAKE_BUILD_TYPE=Release .. && make -j 4
      • Flags passed to compiler: -O3 -DNDEBUG
      • ctest -VV will NOT work here as asserts are turned off;
