[vtkusers] SimpleCocoaVTK problems

[Corrie]

Please see my notes below.  It still appears that CMake doesn't want  
me to compile in GCC 4.0.  I'll let you know how the building goes.

Default compiler has been set to:
gcc version 4.0.1 (Apple Computer, Inc. build 5367)

Then I ran ccmake toward a completely empty build folder.
One of the messages that flashes by is something about checking for a  
working gcc compiler: 3.3. Huh?
After it's done checking, I edit the Carbon/Cocoa fields, the VTKdata  
path field, I toggle the advanced settings and find, among other things:

CMAKE_COLOR_MAKEFILE            *ON
CMAKE_CXX_COMPILER              */usr/bin/g++-3.3
CMAKE_CXX_FLAGS                 *
CMAKE_CXX_FLAGS_DEBUG           *-g
CMAKE_CXX_FLAGS_MINSIZEREL      *-Os -DNDEBUG
CMAKE_CXX_FLAGS_RELEASE         *-O3 -DNDEBUG
CMAKE_CXX_FLAGS_RELWITHDEBINFO  *-O2 -g
CMAKE_C_COMPILER                */usr/bin/gcc-3.3
CMAKE_C_FLAGS

For laughs, I edit the two compiler settings to be 4.0, as seen below

CMAKE_CXX_COMPILER              */usr/bin/g++-4.0
CMAKE_CXX_FLAGS                 *
CMAKE_CXX_FLAGS_DEBUG           *-g
CMAKE_CXX_FLAGS_MINSIZEREL      *-Os -DNDEBUG
CMAKE_CXX_FLAGS_RELEASE         *-O3 -DNDEBUG
CMAKE_CXX_FLAGS_RELWITHDEBINFO  *-O2 -g
CMAKE_C_COMPILER                */usr/bin/gcc-4.0

Then tell it to configure (c)

Then, when I take a peek at those compiler setting again, they're  
baaack:
CMAKE_CXX_COMPILER               /usr/bin/g++-3.3
CMAKE_CXX_FLAGS
CMAKE_CXX_FLAGS_DEBUG            -g
CMAKE_CXX_FLAGS_MINSIZEREL       -Os -DNDEBUG
CMAKE_CXX_FLAGS_RELEASE          -O3 -DNDEBUG
CMAKE_CXX_FLAGS_RELWITHDEBINFO   -O2 -g
CMAKE_C_COMPILER                 /usr/bin/gcc-3.3

Now it's off to the build.  How does one tell which version of GCC  
really was used for a compile?
