Adding Include paths and symbols
For Standard Make projects you can define include paths and preprocessor symbols for the parser.
This enables the parser to understand the contents of the C/C++ source
code so that you may more effectively use the search and code completion
features.
If Autodiscovery is enabled once a build has completed any discovered paths and symbols will be displayed in the Discoverd Paths section. You can also define the properties on a per project basis in the C/C++ Projects or Navigator views.
To add include paths and symbols:
- To set properties for your project right click your standard make project and select Properties.
- Click C/C++ Include Paths and Symbols.

- Select Add Preprocessor Symbol...

and enter your symbol.
- Select Add External Include Path...

and enter your path.
- Select the container and click Edit to change the order in which your new path or symbol is used.

- Select the new object and click Up or Down to move it higher or lower in the order, or you can disable it by clicking Disable.
- Click Finish to close the Edit Container window.
- Click OK to close the Preferences window.
