Can't Find FCL when Installing MoveIt From Source

edit

I'm trying to install MoveIt and OMPL from source to use with ROS Kinetic and catkin tools for compiling. I've created a new catkin workspace.

Following these instructions, I've first downloaded OMPL and FCL in my workspace:

cd moveit_ws/src
git clone https://github.com/ompl/ompl
sudo apt -qq install libccd-dev
git clone https://github.com/flexible-collision-library/fcl
cd fcl
git checkout fcl-0.5
wget https://raw.githubusercontent.com/ros-gbp/fcl-release/debian/jade/fcl/package.xml

I then renamed the project to <name>libfcl-dev</name> in this package.xml as instructed so fcl builds before MoveIt. Next, to install MoveIt:

rosdep update
sudo apt update
sudo apt dist-upgrade
sudo apt install python-wstool python-catkin-tools clang-format-10
source /opt/ros/kinetic/setup.bash
wstool init src
wstool merge -t src https://raw.githubusercontent.com/ros-planning/moveit/master/moveit.rosinstall
wstool update -t src
rosdep install -r --from-paths src --ignore-src --rosdistro ${ROS_DISTRO}

As fcl was already added to my repo, I get this error: libfcl-dev: Cannot locate rosdep definition for [libccd] I instead run:

rosdep install -r --from-paths src --ignore-src --rosdistro ${ROS_DISTRO}
catkin config --extend /opt/ros/${ROS_DISTRO} --cmake-args -DCMAKE_BUILD_TYPE=Release
catkin build

fcl, ompl, and a few of the MoveIt packages compile fine, but moveit-core can't find fcl:

I get the same error when I change the libfcl-dev package name back to fcl and rebuild a couple of times.

Is this a problem on my end? Or is adding a package.xml not enough to turn fcl into a ROS package? Are there other things that should be added to fcl's CMake files? I hacked around and tried to make fcl generate a fclConfig.cmake, but it still wouldn't compile. What else can I do to debug this issue?
