Fix pluginlib_enable_plugin_testing() docstring pitfalls. - #305
Merged
Conversation
The usage example wrapped the APPEND_ENV value in double quotes. CMake passes those quotes through as literal characters in the environment variable value, so tests copying the example end up with a mock install path that is never found at test time. Fix the example and call the pitfall out explicitly. Also document that keeping the default PACKAGE_NAME shadows the real package when it is installed in a prefix which comes earlier in AMENT_PREFIX_PATH (as is the case when a package's own tests run against its install space), in which case pluginlib fails to find the plugin library in the mock install.
