Windows/Linux/Mac Eclipse plugin to compile and upload arduino sketches

Hi,
I've just installed the 3.0 bundle of ecplise and plugin and I've been moving my projects to the eclipse workspace from IDE.. and unfortunately I've run into an issue that I have problems to resolve..

To troubleshoot, I have reinstalled with an empty workspace and one dependency that I have in the project is the RF24 library. Without any coding done - I've just added the library to the project - I get compilation errors..

The library is using a config file that looks at system definitions such as "ARDUINO" in a file called RF24_config.h and my suspicion is that these are not defined.
Any advice on how to verify that the compiler gets the variables?

Much appreciated!
