# Find an RTToolbox installation or build tree.

# When RTToolbox is found, the RTToolboxConfig.cmake file is sourced to setup the
# location and configuration of RTToolbox. Please read this file, or

# definitions. Of particular interest is
#
# RTToolbox_USE_FILE - A CMake source file that can be included
# to set the include directories, library
# directories, and preprocessor macros.
#
# In addition to the variables read from RTToolboxConfig.cmake, this find
# module also defines
#
# RTToolbox_DIR - The directory containing RTToolboxConfig.cmake. This is either
# the root of the build tree, or the lib/InsightToolkit
# directory. This is the only cache entry.
#
# RTToolbox_FOUND - Whether RTToolbox was found. If this is true, RTToolbox_DIR is okay.
#
# USE_RTToolbox_FILE - The full path to the UseRTToolbox.cmake file. This is provided
# for backward compatability. Use RTToolbox_USE_FILE instead.
