CMake Cookbook

Getting ready

The directory layout for this recipe shows the now familiar structure for a superbuild:

.├── CMakeLists.txt├── external│   └── upstream│       ├── CMakeLists.txt│       └── fftw3│           └── CMakeLists.txt└── src    ├── CMakeLists.txt    └── fftw_example.c

The code for our project, fftw_example.c, is located in the src subdirectory and will calculate the Fourier transform of a function defined in the source code.
