# This module defines:
|

#
|
|
# VTK_INSTALL_PATH - Where is the installed version of VTK.
|
|
# USE_BUILT_VTK - Should a built-from-source version of VTK be used.
|

#

# VTK_BINARY_PATH - Where is (one of) the binary tree(s).
|

# USE_INSTALLED_VTK - Should an installed version of VTK be used
|

|

# USE_VTK_FILE - (internal)
|
|
# Full path and location to the UseVTK.cmake file.

# This value changes each time USE_BUILT_VTK or
