This is simpler than specifying all the features individually, but does GDB can read symbol tables from other files, so one solution is to build the package as usual, perhaps with non-optimizing flags (-O0) and with debug symbols (-g) and then split them in executable . If . Since you should never, ever use directory-level commands (like add_compile_options), I'll show you how to use the target-level command instead: There's no need to use the overly generic compile options commands, either.

Just compiling with -g3 will make the binary much bigger but the slowdown of the server should be negligible. following compiler ids as of the If not set, the OUTPUT_NAME target property value or logical target name is used by default. A debug build often results in fast compile times with debugging symbols baked into executables - enabling debugging with tools as such as GDB and LLDB: If the compiler's default standard level is at least that I needed to make a small additional modification to CMakeLists.txt in the project source directory to get an executable built with debugging info and -O0 optimizations (on cmake version 2.8.12.2).
