Provided ITK is installed in one of the canonical locations, CMake should
find it automagically anyway.  It is only when it is located in a
non-standard place that you need to specify ITK_DIR manually.  By default,
the FIND_PACKAGE(ITK) will look in:

    /usr/local/lib/InsightToolkit
    /usr/lib/InsightToolkit

(or on a Windows box it should check the registry for a record of the
install location.)

If you don't and/or can't install it in one of these places, you can always
"prime" CMake by specifying the location in the CMakeCache.txt file (in the
root of your build tree).  Simply create a text file with a line like this:

ITK_DIR:PATH=/home/sdm/projects/lib/InsightToolkit

Then you can copy this cache file into new projects before you run CMake and
it will simply pick up the setting, just like you want.
