CMake can be quite finicky about how variables are passed in from the  
command line.  The correct syntax is:

-DVAR_NAME:TYPE=VAL

Try: -DCMAKE_BUILD_ARCH:STRING=32 and see if you still have  
problems.  If you don't see it on the very first page in ccmake, then  
it didn't pick it up properly.

Sadly, cmake doesn't give warnings or errors if the other form is  
used (-DVAR_NAME=VAL).  It just behaves erratically.
