cannot find -lfcl using fcl library

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(
)


generate_messages(
    DEPENDENCIES
    geometry_msgs sensor_msgs nav_msgs visualization_msgs  
)


catkin_package(
    INCLUDE_DIRS include
    LIBRARIES ${haptic_teleoperation}
    CATKIN_DEPENDS message_runtime nav_msgs roscpp sensor_msgs 
    DEPENDS eigen
)

add_dependencies(fcl_test

target_link_libraries(fcl_test
    fcl
    ${catkin_LIBRARIES}
    ${Boost_LIBRARIES}
    ${OpenCV_LIBRARIES}

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.
