CMake Cookbook

How it works

We have demonstrated how to set a default build type and how to override it from the command line. With this, we can control whether a project is built with optimization flags or with all optimizations turned off, and instead debugging information on. We have also seen what kind of flags are used for the various available configurations, as this depends on the compiler of choice. Instead of printing the flags explicitly during a run of CMake, one can also peruse the output of running cmake --system-information to find out what the presets are for the current combination of platform, default compiler, and language. In the next recipe, we will discuss how to extend or adjust compiler flags for different compilers and different ...
