Hello, ROS experts.
I referenced below two link.
- [link1](https://answers.ros.org/question/231199/using-catkin-to-install-pre-made-libraries/)
- [link2](https://github.com/ros-drivers/prosilica_gige_sdk/blob/32aea9be0de7e40c647166d5f54de09948635b9f/CMakeLists.txt#L149)
On my project, there are two packages. For our convenience, I'll call these A and B project.
- A project: This project have a general library, a pre-made library. (there are two library)
- B project: This project will use two library from A project.
--> There project placed on same catkin_workspace.
> The problem is that I can't not use **pre-made library** on **B project**.
detail: I succeed it to install the pre-made library on `catkin_ws/devel/lib`. But, when I build the project B, It can not find pre-made library.
How can I fix this issue?
There is more detail on below description.
