I'm right now investigating if CLion might be a good solution for the development process of my phantomjs-cef project (https://github.com/aknuth/phantomjs-cef). The base of it is the Chromium Embedded Framework (https://bitbucket.org/chromiumembedded/). This one is CMake based and the import into CLion run smoothly.
Starting the cefclient executable in "RUN MODE" works out the box from the IDE but "Debug MODE" does not come up neither with breakpoints nor without them.
Does anyone tried to work successfully with Chromium Embedded Framework inside CLion ?
