 ## Link with powsybl-iidm4cpp
 We provide cmake script files that make it easy to use `powsybl-iidm4cpp` in a CMake project, that are installed in the `<PREFIX>/LibIIDM/cmake` folder.
 
 To use the library in your project, add the `find_package` instruction to your `CMakeLists.txt` file:
 ```
 find_package(LibIIDM REQUIRED)
-``` 
+```
 
 Then configure your project passing the `-DCMAKE_PREFIX_PATH=<IIDM4CPP_PREFIX>` option to the cmake command:
 ```
 $> cmake ... -DCMAKE_PREFIX_PATH=<IIDM4CPP_PREFIX>
