New roslint command results in 'Unknown CMake command'

[lucasw]

I'm experimenting with a roslint_rust() in https://github.com/lucasw/roslint/blob/roslint_rust/cmake/roslint-extras.cmake.em, and I have that roslint and my_package wanting to use roslint_rust in the same catkin workspace, but trying to use the new roslint results in:

catkin build my_package --no-deps --verbose --catkin-make-args roslint
...
  Unknown CMake command "roslint_rust".

Do I need additional modifications to roslint-extras.cmake.em to expose the new command? Or is there something else that needs to be recompiled to make use of the overlaid custom version of roslint?

Current work-around is to define the roslint_rust function within my_package

function(roslint_rust)
  _roslint_create_targets()
  add_custom_command(TARGET roslint_${PROJECT_NAME} POST_BUILD
                     WORKING_DIRECTORY ${PROJECT_SOURCE_DIR}
                     COMMAND ${CATKIN_ENV} cargo clippy -- -D warnings VERBATIM)
endfunction()

roslint_rust()

You need to tell catkin about your extras:

Whoops, it turned out I just needed to do a full catkin clean first, I thought I could get away with deleting just build/my_package and devel/.private/my_package.
