Getting couldn't find package errors for open_cv with ROS

edit

So I had a repository that compiled before but couldn't find an executable. I uploaded this to my Drive and have now re-downloaded and it granted permissions so it still has the right dependencies and such.

In CMakeLists.txt :

find_package(catkin REQUIRED COMPONENTS   roscpp   rospy   std_msgs   sensor_msgs> ``  
image_transport   cv_bridge )  find_package(OpenCV) 
include_directories(${OpenCV_INCLUDE_DIRS})
target_link_libraries(my_awesome_library ${OpenCV_LIBRARIES})

And in package.xml:

  <buildtool_depend>catkin</buildtool_depend>
  <build_depend>roscpp</build_depend>
  <build_depend>std_msgs</build_depend>
  <build_depend>sensor_msgs</build_depend>
  <build_depend>image_transport</build_depend>
  <build_depend>cv_bridge</build_depend>
  <build_depend>opencv2/highgui/highgui.hpp><build_depend>

  <build_export_depend>roscpp</build_export_depend>
  <build_export_depend>std_msgs</build_export_depend>
  <build_export_depend>sensor_msgs</build_export_depend>
  <build_export_depend>cv_bridge</build_export_depend>

  <exec_depend>roscpp</exec_depend>
  <exec_depend>rospy</exec_depend>
  <exec_depend>std_msgs</exec_depend>
  <exec_depend>sensor_msgs</exec_depend>
  <exec_depend>image_transport</exec_depend>
  <exec_depend>message_runtime</exec_depend>
  <exec_depend>opencv2/highgui/highgui.hpp<exec_depend>

I then ran:

devel/setup.bash

Followed by:

rosdep install --from-paths /home/phil/catkin_ws/src --ignore-src

This worked fine but then I still get the errors:

-- +++ processing catkin package: 'camera'
-- ==> add_subdirectory(camera)
-- Could NOT find vision_opencv (missing: vision_opencv_DIR)
-- Could not find the required component 'vision_opencv'. The following CMake error indicates that you either need to install 
the package with the same name or change your environment so that it can be found.
CMake Error at /opt/ros/melodic/share/catkin/cmake/catkinConfig.cmake:83 (find_package):
Could not find a package configuration file provided by "vision_opencv"
with any of the following names:

vision_opencvConfig.cmake
vision_opencv-config.cmake

Add the installation prefix of "vision_opencv" to CMAKE_PREFIX_PATH or set
"vision_opencv_DIR" to a directory containing one of the above files.  If
"vision_opencv" provides a separate development package or SDK, be sure it
has been installed.

This is my repository: https://github.com/MightyFunkster/Cam...

It sort of seems like I've not installed OpenCV correctly but it compiled completely fine with the same repository before I uploaded it :(

I'm using Apache NetBeans, OpenCV 2 and Ubuntu 18.04.4 LTS. It seems strange that it can't find opencv_vision.
