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 and debug symbol files. CPack, like CMake itself, is a CLI program. CMakeLists.txt also may set some of variables CMAKE__FLAGS_, if default setting for compiler is not suited for the project.
