[ITK-dev] installed ITK cannot be moved due to absolute path

Tue Dec 20 10:15:03 EST 2016

Hi Rashad,

one way to generate install tree in a different location is by
changing CMAKE_INSTALL_PREFIX in CMake, reconfiguring, regenerating
project, the building the INSTALL target. That should generate the install
tree in your desired location.

Dženan
