Message:
I attached a patch for cmake. It works on OS X 10.4 (finds nothing) but
untested on OS X 10.5+ (should find the header file and add support for
aqueue).

It also removes the #ifdef that surrounds the aqueue.m file, as that file
will be excluded from the build if cmake fails to find the appropriate
header file.

Message:
Actually, I don't think there is anything in the header files that could be
selectively disabled by the user's program settings, so the #error comment
is probably irrelevant.

Message:
Would it be sufficient to check for the existence of
AudioToolbox/AudioQueue.h when cmake runs? Then the #ifdefs could be
changed into #errors if the target is 10.4 at user program compile time.

Message:
The attached patch should fix the problem. Note that the entire source file
for the aqueue driver is contained in an "#if MAC_OS_X_VERSION_MIN_REQUIRED
>= 1050 / #endif" block.
It's arguably better to do this from within CMake, but I'm not entirely
sure how to do that.
