[Insight-users] Re : Re : ITK v4 + IO factory classes : runtime error

[Matt McCormick]

Hi James,

You want to have

  find_package(ITK REQUIRED)
  include(${ITK_USE_FILE})

In your CMakeLists.txt.  Then, set ITK_DIR in your cmake build
configuration.  The ITK_DIR will allow you to point to different ITK
builds.

Hope this helps,
Matt
