iOS status and how-to about rtmidi HOT 4 OPEN

For anyone reading this, for now I've resolved this by doing the below in my CMakeLists.txt:

if (IOS)
    target_compile_definitions(rtmidi PRIVATE TARGET_OS_IPHONE=1)
endif()

But setting this is actually the responsibility of #include <TargetConditionals.h> as far as I know. So I doubt this is the way to go. Not sure if I should do something different on my end, or if there's in issue in rtmidi.

PS: I first tried to #include <TargetConditionals.h> before including RtMidi.h, but this did not help.

I'm completely lost here... Could you perhaps give some more details on how to set this up? Thank you

@GarrettFleischer What is your issue precisely? For what it's worth, here's my static lib's CMakeLists.txt where you can see

target_compile_definitions(rtmidi PRIVATE TARGET_OS_IPHONE=1)

@izzyreal thank you for the response, I was able to do it through creating a new xcode project
