The code for this recipe is available at https://github.com/dev-cafe/cmake-cookbook/tree/v1.0/chapter-05/recipe-05 and has a Fortran example. The recipe is valid with CMake version 3.5 (and higher) and has been tested on GNU/Linux, macOS, and Windows with MSYS Makefiles.
This recipe will show how to use the second signature of add_custom_command to perform custom operations without output. This is useful to perform certain operations right before or right after a specific target is built or linked. Since the custom commands are only executed if the target itself has to be built, we achieve target-level control over their execution. We will demonstrate this with an example where we print the link line of a target right before it is built, and then we measure the static size allocation of the compiled executable right after...
