[Insight-users] cmake question

[William A. Hoffman]

To reference an evnironment variable in cmake you do this:
$ENV(VAR), so this:

 LINK_DIRECTORIES(
${VTKQT_LIBRARY_PATH}
)

Is most likely doing nothing.  To see the commands used, you can
do make VERBOSE=1.

I would recommend using a FIND_LIBRARY call in the cmake file
to find the VtkQt library.   CMake is meant to avoid the use
of environment variables if possible.
