I think there may be a bug in the introjucer: when "Copy the module into the project folder" is set on a module in the introjucer, the include paths in Xcode point to ../../JuceLibraryCode/ and ../../JuceLibraryCode/modules, but are set as "non-recursive" (in the xcodeproj).
The module gets copied into a subdirectory in JuceLibraryCode, for example: .../JuceLibraryCode/modules/juce_gui_extra/juce_gui_extra.h.
As a result, when compiling, xcode can't find juce_gui_extra.h
Is this a bug, or am I doing something wrong?
(btw I chose this forum over the mac-specific forum, I hope that was correct. thx.)
