I'd just like to mention that the Mac community would dearly love to see
cross-compilation support in cmake.

Are you familiar with Apple's concept of a "Universal Binary":
<http://en.wikipedia.org/wiki/Universal_binary>

Basically, it's a kind of cross compilation.  On a PowerPC Mac you can
compile your executable for both PPC and Intel Macs, and vice versa. 
CMake does support Universal Binaries actually, you may want to see this
bug for background:
<http://www.vtk.org/Bug/bug.php?op=show&bugid=2492>

However, the whole idea of TRY_COMPILE is of course incompatible with
this, since the minute you assume that the machine doing the building is
the same type as the machine you are building for, you are in trouble...
