## An rviz plugin is just a shared library, so here we declare the
## library to be called ``${PROJECT_NAME}`` (which is
## "rviz_plugin_tutorials", or whatever your version of this project
## is called) and specify the list of source files we collected above
## in ``${SRC_FILES}``.

## Link the myviz executable with whatever Qt libraries have been defined by
## the ``find_package(Qt4 ...)`` line above, or by the
## ``set(QT_LIBRARIES Qt5::Widgets)``, and with whatever libraries
## catkin has included.
##
## Although this puts "rviz_plugin_tutorials" (or whatever you have
## called the project) as the name of the library, cmake knows it is a
## library and names the actual file something like
## "librviz_plugin_tutorials.so", or whatever is appropriate for your
## particular OS.
