Error building from source on Mac

[Peter Hull]

If I checkout from git and attempt to build with `sh gradlew` I get this error:

/Projects/jfx/modules/javafx.graphics/src/main/native-glass/mac/GlassTouches.m:122:14:
error: comparison of different enumeration types ('CGEventType' (aka
'enum CGEventType') and 'enum NSEventType') [-Werror,-Wenum-compare]
  122 |     if (type == NSEventTypeGesture)
      |         ~~~~ ^  ~~~~~~~~~~~~~~~~~~
1 error generated.

> Task :graphics:ccMacGlass FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':graphics:ccMacGlass'.

Is this a bug? I am not sure of the purpose of this code but as far as
I know CGEventType is not 'toll-free bridged' to NSEventType and I
don't see a CGEventType that corresponds to NSEventTypeGesture. So
potentially this branch could be taken incorrectly - or it may be
absolutely fine.

For info I am using these versions:

OpenURIHandler events not received by AWT when JavaFX is primary
toolkit

(I know I should ideally be using JDK24 for this but it's not in
homebrew yet and I don't think this problem in the native code is
caused by a Java version mismatch)
