Bah.  I finally found the problem.  All of my string handling was 
correct.  I was passing arguments to a CMake script using 
INCLUDE(${CMAKE_CURRENT_BINARY_DIR}/vars.cmake) because there are no 
command line arguments for scripts in CMake 2.4.2.  *That* file was 
missing the quotes.  Bah!  Well I look forward to being able to pass 
command line arguments in the next release.  This is another reason why 
they're needed: people will be forever breaking their own homebrew hacks 
around the problem.  That one only cost me, oh, 2 hours at least.
