The find_package command will use ITK_DIR without searching at all if it is set.
I can't reproduce your problem.  CMake 2.8.4 finds ITK for me in all the cases
it used to find it plus more.  Setting ITK_DIR hands it the answer and it works.
Please send a complete sample CMakeLists.txt that shows this problem along with
a listing of the contents of ${ITK_DIR} on your disk.

Thanks,
