No, it wasn't there.  Thanks for pointing this out.

Doesn't it seem odd that CMake knew enough to complain that 
OPENGL_INCLUDE_DIR wasn't set correctly, but didn't know enough to see 
if the value I gave it was useless, because the file it needed wasn't 
there?

Apple doesn't make them available anymore, but I found something that 
seemed to work at:
<http://vuiis.vanderbilt.edu/~martinbw/Download/MacOSX>
The X11SDKForMacOSX.dmg file created the GL header files in 
/usr/X11R6/include/GL.

Then, when I tried again to compile, eventually I got:

Now, the "illegal reference to symbol: _crc32" I've seen before, and I 
fixed it (based on Mathieu Malaterre's advice) by manually adding "-lz" 
to the end of the link line.  As for the missing _glX symbols, I made 
them go away by manually adding "-lGL" to the link line.  And the "vtk" 
binary compiled!

And then, when I tried to run it, it completely ignored X windows (it 
ran even though I hadn't launched X11 on the mac), and popped up the 
initial wish window, which generated "SetFrontProcess failed,-606" 
error messages when I clicked on it. So it didn't end up using X after 
all, even though I turned off Carbon and Cocoa in cmake:
<http://www.sci.utah.edu/~gk/vtk/CMakeCache.txt>

I would be very grateful for further help in getting a functional 
VTK/Tcl/Tk compiled on a mac.
