1. Get Info on the WarpMap_0.1 target and click the Build Settings tab
2. At the top of the Build Settings is a search box, type Syphon into that
3. One of the settings that will show up is “FRAMEWORK_SEARCH_PATHS_QUOTED_FOR_TARGET_2” with the value of “$(SRCROOT)/../../../addons/ofxSyphon/libs/Syphon/lib/osx”
4. Make sure that points to the correct location of ofxSyphon relative to your project (each ../ is travelling up one level in the folder structure)
any idea is we would be able to do so in Linux one day ?
One day if Linux adds the requisite features, maybe. Now, no. http://syphon.v002.info/faq.php
