Please update your cmake version to 1.4 patch 3 for ITK development. Although it is not required right now, it is now OK to start using cmake 1.4 features in ITK. If you are using the binary on windows, you can simply check for updates. For unix, there are several binaries available at www.cmake.org. If you are building cmake from cvs, you can do an update -r LatestRelease. -Bill
