/**
 * @brief CMake plugin for CodeLite.
 *
 * Here is an explanation how the plugin works. For each project a makefile
 * is generated with code that calls cmake if there is no Makefile in build
 * directory (create directory if missing). Then is generated code built by
 * calling make in build directory. Changes in CMakeLists.txt is detected
 * by Makefile generated by cmake. Some CMakeLists.txt can contains code that
 * takes all source files in specific directory and doesn't list them
 * directly. In this case if a source file is added or removed the plugin
 * doesn't regenerate CMake files because it's not able to detect changes.
 * For this purpose there is a button that marks configuration dirty and
 * forces plugin to regenerate CMake files.
