 +===== Use KDevelop with Existing Build Configuration =====
 +If you have previously built your application manually or with the aid of the EEROS build scripts ([[https://github.com/eeros-project/eeros-build-scripts]]), you can import the configuration into KDevelop as follows:
 +  - Import the project by choosing the ''CMakeLists.txt'' of your project.
 +  - Right click on the project and open the project configuration panel.
 +  - Choose the build directory of the previously built application as your build directory
 +  - Leave the entries for install directory, build type, and extra arguments empty. These settings will be fetched from the existing CMake configuration in your build directory.
 +  - Click ''Ok''
 +  - Build
