Yesterday, I committed a whole bunch of changes to the CMakeLists.txt
files in the main trunk of the vxl repository to take advantage of
CMake 1.4 features. This means that vxl will no longer build with a
CMake version before 1.4. Please update accordingly.
The most important new feature is dependency analysis, which allows us
to dispense with the CMakeListsLink.txt files, and also reduces the
link lines considerably.
