CMake Cookbook

Getting ready

This recipe will build a simple executable linking against the message library. The layout of the project is as follows:

├── cmake│   ├── install_hook.cmake.in│   └── print_rpath.py├── CMakeLists.txt├── external│   └── upstream│       ├── CMakeLists.txt│       └── message│           └── CMakeLists.txt└── src    ├── CMakeLists.txt    └── use_message.cpp

The main CMakeLists.txt file coordinates the superbuild. The external subdirectory contains CMake instructions to handle the dependencies. The cmake subdirectory contains a Python script and a template CMake script. These will be used to fine-tune the installation, the CMake script being first configured and then executed to call the Python script to print the RPATH for the installed use_message executable:
