[vtkusers] Vtk programming on Mac OS X with Xcode

You have to know how VTK was built? Was it built against Carbon or  
Cocoa? After you find that out then you can include the proper system  
frameworks in your Xcode project such as CoreFoundation.framework or  
Cocoa.framework or Carbon.framework. If you use the CMakeLists.txt  
that come with each example you can generate a fully working Xcode  
project by doing:

cmake [path/to/source] -G Xcode

This will generate the Xcode project. If you are just doing the  
example and just want to see it run then you can always just do:

cmake [path/to/source]   (This assumes an 'out of source' build)

Makefiles will be generated and then you can type 'make' and then run  
the resulting executable. CMake will take care of getting all the  
proper libraries and frameworks linked into your executable.

Here is what I did:

514:[mjackson at Thor:Cxx]$ mkdir Build
515:[mjackson at Thor:Cxx]$ cd Build
516:[mjackson at Thor:Build]$ cmake ../
-- Check for working C compiler: /usr/bin/gcc
-- Check for working C compiler: /usr/bin/gcc -- works
-- Check size of void*
-- Check size of void* - done
-- Check for working CXX compiler: /usr/bin/c++
-- Check for working CXX compiler: /usr/bin/c++ -- works
-- Configuring done
-- Generating done
-- Build files have been written to: /Users/Shared/OpenSource/ 
517:[mjackson at Thor:Build]$ make
Scanning dependencies of target Cone
[100%] Building CXX object CMakeFiles/Cone.dir/Cone.o
Linking CXX executable Cone
[100%] Built target Cone
518:[mjackson at Thor:Build]$ ./Cone

The cone program goes pretty quick so watch out for it.

Lastly, if you are doing purely C++ VTK Code and NOT going to employ  
anything Mac OS X specific (Windowing/GUI) then you could use Eclipse  
+ CDT as your IDE. I have written a tutorial about using it with CMake.
