cmake error package is considered to be NOT FOUND

edit

I am working on laser_assembler porting to ROS2. Laser assembler is dependent on filters package. So before compiling laser_assembler package I am sourcing filters package path.

While compiling laser_assembler package I get following error:

CMake Error at CMakeLists.txt:27 (find_package):

Found package configuration file:
  /home/root-pc/vandana/laser/ros2_ws_filters_swati/ros2_ws_filters_test1/install/filters/share/filters/cmake/filtersConfig.cmake

but it set filters_FOUND to FALSE so package "filters" is considered to be
NOT FOUND.

Does anyone know what is the issue here ? why am I getting this error for colcon build ?
