[CMake] CMake and GDB

[Nils Gladitz]

"cmake -DCMAKE_BUILD_TYPE=Debug" should be enough to get gdb debuggable 
binaries.
Is the process which you intend to debug running when you ask gdb for a 
backtrace?
You will only be able to get a backtrace if the process has been started 
and has not yet exited.

e.g.:
gdb ./mybin
break main
run
backtrace
