Seems like on the latest develop branch the CLion exporter is broken on Mac, even when using the default GUI app or default plugin template.
The CMake file itself has errors during parsing.
The problem seems to be related to this line
XCODE_ATTRIBUTE_MTL_HEADER_SEARCH_PATHS ( "../../JuceLibraryCode", "/Users/eyalamir/Code/JUCE/modules", )
Changing the few appearances of this line manually to:
XCODE_ATTRIBUTE_MTL_HEADER_SEARCH_PATHS "../../JuceLibraryCode, /Users/eyalamir/Code/JUCE/modules"
Seems to fix it and build correctly.
