Do I need to install a ros package in order to use its libraries in the same catkinws?

I have a project in a catkin workspace. I'm developing it inside a docker container and this is my only alternative. For this reason I do not want to install any package, as the containers are not persistent.

I have several packages inside the catkin directory and some of then are plugins libraries. I would like to use the libraries of my package A in the package B without installing the package A. I have not been able to do this using the cmake command

find_package(catkin REQUIRED COMPONENTS packageA)

include_directories(${catkin_INCLUDE_DIRS})

target_link_libraries(package_B_node ${catkin_LIBRARIES})

to add the required includes and the libraries

Can you git clone or otherwise copy the source of package A into the catkin_ws alongside package B?

Or create a new docker image that uses the base docker image you can't alter as a starting point in the Dockerfile and then install package A as the only additional step?

Yes I can. The problem is that I forgot the following signature of the catkin_package command in the CMakeLists.txt of the packageA

catkin_package(INCLUDE_DIRS include LIBRARIES plugin_triangle polygons)

without these arguments incatkin_package catkin did not generate the right information in catking_workspace/devel/share/packageA/cmake/packageAConfig.cmake in order to expose the address of the headers and the libraries in the ${catkin_INCLUDE_DIRS} and ${catkin_LIBRARIES} inside the CMakeList.txt of packageB once the find_package function is called.
