| """The cmake plugin is useful for building cmake based parts. | |
| These are projects that have a CMakeLists.txt that drives the build. | |
| The plugin requires a CMakeLists.txt in the root of the source tree. | |
| This plugin also supports options from the `make` plugin. Run | |
| `snapcraft help make` for more details. | |
| This plugin uses the common plugin keywords as well as those for "sources". | |
| For more information check the 'plugins' topic for the former and the | |
| 'sources' topic for the latter. | |
| Additionally, this plugin uses the following plugin-specific keywords: | |
| - configflags: | |
| (list of strings) | |
| configure flags to pass to the build using the common cmake semantics. | |
