# - try to find JTTK library
#
#  JTTK_LIBRARY_DIRS, library search path
#  JTTK_INCLUDE_DIRS, include search path
#  JTTK_{component}_LIBRARY, the library to link against
#  JTTK_ENVIRONMENT, environment variables to set
#  JTTK_RUNTIME_LIBRARY_DIRS
#  JTTK_FOUND, If false, do not try to use this library.
#
# If you have license issues, you might run this command on each JtTk-using target:
#  jttk_stamp_binary(<targetname>)
#
# Plural versions refer to this library and its dependencies, and
# are recommended to be used instead, unless you have a good reason.
#
# Useful configuration variables you might want to add to your cache:
#  JTTK_ROOT_DIR - A directory prefix to search
#                         (a path that contains include/ as a subdirectory)
