[ros2] opening some of the rclcpp examples in CLion [closed]

edit

Hey guys!

I am struggling with opening the rclcpp examples provided from here: https://github.com/ros2/examples/tree...

in CLion 2017.3.

What i did:

• open the terminal
• source my workspace
• run the startup shell script for clion
• opened the publisher example and the client example successfully (everything working fine, all symbols got imported and work).

The problems start when i tried to open the minimal_composition example. CMake fails during opening. However, i can build the workspace using 'ament build' and i can run cmake on the CMakeLists.txt from minimal_composition manually using the exact same command as CLion gives in the log window. However, this is the output from CLion:

and this is the output from manual cmake from within a build folder located in the minimal_composition package:
