[Insight-users] question about fltk to VTK FltkImageViewer

[Luis Ibanez]

Hi Uzay,

If you took that application out of the InsightApplications
source tree, then the variables

      InsightApplications_SOURCE_DIR
      InsightApplications_BINARY_DIR

Will not be defined.

CMake defines those variables in response to the command

      PROJECT( InsightApplications )

so, once you take this app out of the source three,
such command line is not parsed by CMake anymore.

You will have to define those two variables manually,
or set them using CMake commands such that the user
will see them when she/he runs CMake.

Something like

SET(InsightApplications_SOURCE_DIR "c:\src\InsightApplications")
SET(InsightApplications_BINARY_DIR "c:\bin\InsightApplications")

at the top of your CMakeLists.txt file, or at least before you
make any reference to InsightApplications_SOURCE_DIR
or InsightApplications_BINARY_DIR




   Regards,



      Luis
