[ITK-users] Pointing CMake to Updated ITK Library

[Matt McCormick]

Hi Davis,

The ITK build to use is usually selected in the CMake build
configuration (not in the source file CMakeLists.txt), by setting the
"ITK_DIR" variable.  This should point to the path that has the
desired ITKConfig.cmake file.

HTH,
Matt
