################################################################################ # # CMake script for finding An Orocos RTT Plugin in case you require it during build time. # If the optional RTT_COMPONENT_PATH environment variable exists, header files and # libraries will be searched in the RTT_COMPONENT_PATH/include and RTT_COMPONENT_PATH/lib/orocos/plugins # directories, respectively. Otherwise the default CMake search process will be # used. Use the RTT_HINTS variable to hint the location of the orocos-rtt installation directory. # # Usage: find_package( RTTPlugin COMPONENTS rtt-scripting ) # # This script creates the following variables: # RTT_PLUGIN_<COMPONENT>_FOUND: Boolean that indicates if the plugin was found # RTT_PLUGIN_<COMPONENT>_INCLUDE_DIRS: Path to the plugin header files (equal to OROCOS_RTT_INCLUDE_DIRS) # RTT_PLUGIN_<COMPONENT>_LIBRARIES: Plugin library for the current OROCOS_TARGET cmake or environment variable. # RTT_PLUGIN_<COMPONENT>_<OROCOS_TARGET>_LIBRARIES: Plugin library for the current OROCOS_TARGET cmake or environment variable (same as above). # ################################################################################
