CMake Cookbook

Getting ready

As shown in Chapter 7, Structuring Projects, we will structure our project as a tree. Each subdirectory has a CMakeLists.txt file with instructions pertaining to that directory. This allows us to confine as much information as possible within the leaf directories as in this example:

.├── CMakeLists.txt└── src    ├── bt-randomgen-example.f90    ├── CMakeLists.txt    ├── interfaces    │   ├── CMakeLists.txt    │   ├── interface_backtrace.f90    │   ├── interface_randomgen.f90    │   └── randomgen.c    └── utils        ├── CMakeLists.txt        └── util_strings.f90

In our case, we have a src subdirectory containing the sources, including bt-randomgen-example.f90, our executable. Two further subdirectories, interfaces and utils, contain more source code that will be compiled ...
