# facilitate existing CMake builds which handle things like bundle creation, icons, plists, and

# This option controls whether dummy targets are added to the build, where these targets contain all
# of the source files for each JUCE module. If you're planning to use an IDE and want to be able to
# browse all of JUCE's source files, this may be useful. However, it will increase the size of
# generated IDE projects and might slow down configuration a bit. If you enable this, you should
# probably also add `set_property(GLOBAL PROPERTY USE_FOLDERS YES)` to your top level CMakeLists,
# otherwise the module sources will be added directly to the top level of the project, instead of in
# a nice 'Modules' subfolder.
