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.

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.
