When CMAKE_BUILD_TYPE is Debug and we are compiling with GCC, add the following options to CMAKE_C_FLAGS and CMAKE_CXX_FLAGS: -O0 -fno-omit-frame-pointer -fno-inline Ditto for Clang, except that -fno-inline-functions is used instead of -fno-inline. cf. thread starting at https://sourceforge.net/p/flightgear/mailman/message/36295412/
