2. In your project root directory, create the project's Makefiles:

   cmake -G 'Eclipse CDT4 - Unix Makefiles'

3. Import the project using Eclipse->File->Import->General->Existing Projects

4. Enjoy code completion using Ctrl-Space

For Python

1. Install PyDev
2. In Eclipse Navigate to... Window->Preferences->PyDev->Interpreters
3. Configure PyDev, selecting the Python interpreter to be used
4. Add /usr/local/lib/python2.7/dist-packages (or other valid path(s)) to the System Libraries
