I use my own variable -DCMAKE_BUILD_ARCH=32 to determine whether I

The problem is that cmake now goes to check compiler and it runs
Platform/UnixPaths.cmake without passing any of my variables to it
(ie. CMAKE_BUILD_ARCH="").
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.
