Christoph, Of course. That’s why Cmake provides CMAKE_BUILD_TYPE. To make a debug build, add the argument -D CMAKE_BUILD_TYPE=Debug to your cmake invocation. BTW, the flags passed to the compilers are also modifiable from the command line using CMAKE_C_FLAGS and CMAKE_CXX_FLAGS. No need to change CMakeLists.txt. Should you ever need to do this for an autotools project the equivalents are the environment variables CFLAGS and CXXFLAGS; autotools also reads CPPFLAGS and applies the contents to both c and c++ compiles. Autotools unfortunately doesn’t have an equivalent to CMAKE_BUILD_TYPE so you have to adjust the compiler flags.
