Using an environment variable to point to a library is a common practice. Allows freedom to try updates to that library and allows everyone involved in the project to have their library stored in a different place.
I created an environment variable $JUCE_HOME on my mac and then opend the .jucer file in a text editor.
Since there is no way to enter the path to JUCE home folder in Introjucer - I replaced the hard path with $(JUCE_HOME)/modules (for each of the modules listed)
If I now open this with Introjucer and then generate the project/open it in XCode - not only is the $(JUCE_HOME) missing from the header search paths in the project settings, but it somehow generates almost completely empty AppConfig.h file
Am I doing something wrong, is there a workaround (except using relative folders which is obvious) or is this not possible at the time?
