[Insight-users] extracting an application

[Karthik Krishnan]

Most likely, VTK simply wasn't found. Post the value of VTK_DIR in your
CMakeCache.txt. If there is a NOT_FOUND there, you need to set VTK_DIR
to the VTK binary directory while configuring using CMake. See the
documentation of the FIND_PACKAGE command:

http://cmake.org/HTML/Documentation.html

To be correct, since your project *requires* VTK, you should have 
FIND_PACKAGE( VTK REQUIRED )
instead of 
FIND_PACKAGE( VTK )

The latter implies that it is optional. (as in InsightApplications,
where only a few apps require VTK). This will ensure that your project
never gets configured if VTK isn't found.

HTH,
