cannot find -lfcl using fcl library - cmake

Question

I want to run a ROS node using fcl library. I just wrote a small code and I edited the CMakeLists.txt to make sure that I can run the node but I got the following error:
/usr/bin/ld: cannot find -lfcl
collect2: error: ld returned 1 exit status
What should I do?
My CMakeLists.txt is the following:
cmake_minimum_required(VERSION 2.8.3)
project(package_name)
find_path(FCL_INCLUDE_DIRS
NAMES fcl/collision.h
HINTS ${PC_FCL_INCLUDEDIR}
PATHS "${CMAKE_INSTALL_PREFIX}/include")
find_package(catkin REQUIRED COMPONENTS
nav_msgs
roscpp
sensor_msgs
visualization_msgs
tf
dynamic_reconfigure
message_generation
laser_geometry
geometry_msgs
cmake_modules
)
find_package(Boost REQUIRED)
find_package(Eigen REQUIRED)
find_package(PCL REQUIRED)
find_package(OpenCV REQUIRED)
find_package(fcl REQUIRED)
generate_dynamic_reconfigure_options(

Answer 1

Replace fcl by ${fcl_LIBRARIES} in the link-command:
target_link_libraries(fcl_test
${fcl_LIBRARIES}
${catkin_LIBRARIES}
${Boost_LIBRARIES}
${OpenCV_LIBRARIES}
)
If find_package(fcl REQUIRED) works correctly, this variable should be automatically set.
