Documentation: how to change juce macro definitions "JucePlugin_xxx"

[zeebyezon]

I read all the doc carefully and I could not figure out how to set for example JucePlugin_WantsMidiInput=1.
I see it is set to 0 on the command line.
I tried to define it in the CMakeLists.txt of the source directory (target_compile_definitions(SharedCode...): it works on Windows but produces a lot of warnings on linux and mac.

How are we supposed to do?
This should be documented.
(sorry if I missed something)

Adding NEEDS_MIDI_INPUT=1 to target_compile_definitions should work.

See https://github.com/juce-framework/JUCE/blob/master/docs/CMake%20API.md

Thank you zsliu98. Actually no, it does not work.
But thanks to your response, I searched for NEEDS_MIDI_INPUT and found an example with the comment
# NEEDS_MIDI_INPUT TRUE/FALSE # Does the plugin need midi input?
in juce_add_plugin().
So what I need is to add NEEDS_MIDI_INPUT TRUE inside the juce_add_plugin. And there it works.

Would be great to have it documented.
Thanks again.

It's a good idea to add some docs for how to setup a synth vs. instrument... ultimately they are all just calls to juce_add_plugin, but at the very least we can link out there.
