[CMake] What the... Can't seem to change CMAKE_INSTALL_PREFIX

[kent williams]

We call cmake from inside our top level Makefile to build ITK.  To
that end we specify the CMAKE_INSTALL_PREFIX on the command line.

I've appended our whole cmake command line at the end of this message
but the operative thing is that the CMake command line includes:
-DCMAKE_INSTALL_PREFIX:PATH=/scratch/kent/brains2/MACOSX/DEBUG/src

But try as I might, the CMakeCache.txt after configuring Insight contains this:

//Install path prefix, prepended onto install directories.
CMAKE_INSTALL_PREFIX:PATH=/usr/local

What the heck is going on here?  This is using a recent snapshot if ITK CVS.
