how to use static library which find_package() by another catkin package

edit

this is my workspace tree

  .
    └── src

        │   ├── CMakeLists.txt
        │   ├── include

I would like to use static library which in my case I want to use PCL library that locate at ./src/pkg_pcl/include/pkg_pcl I want to create catkin package that find this library then share it with another package. so ./src/pkg_pcl/CMakeLists.txt might look like this

cmake_minimum_required(VERSION 3.0.2)
project(pkg_pcl)

find_package(PCL REQUIRED NO_DEFAULT_PATH  PATHS ${CMAKE_CURRENT_SOURCE_DIR}/include/pkg_pcl)

and ./src/pkg_b/CMakeLists.txt just look like this :

cmake_minimum_required(VERSION 2.6 FATAL_ERROR)
project(pkg_b)

find_package(pkg_pcl)

NOTE : I want package pkg_b to use find_package(pkg_pcl) which can link to PCL library instead of find_package(PLC) which might find package in shared library.

is it possible to do this ?
