dj_sdk when cloning grvc_ual

[ToufikSouanef]

Hello
I was following what is explained in the wiki. I have installed dji sdk (in src folder) However i get the following error:
Could not find the required component 'dji_sdk'. 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/kinetic/share/catkin/cmake/catkinConfig.cmake:83 (find_package):
Could not find a package configuration file provided by "dji_sdk" with any
of the following names:
dji_sdkConfig.cmake
dji_sdk-config.cmake

Hi,

Unfortunately, the backend_dji_ros version is a bit deprecated with recent versions of DJI SDK, since its last update was before the end of 2019. In fact, one of the changes in DJI SDK was the package name, and that is why it does not find the package. I am afraid that if you want to use UAL with DJI you have two options:

• Use previous versions of the DJI SDK (I think v3.8.1 should be fine).
• Fix the current backend_dji_ros to make it work with the latest DJI SDK versions and make a pull request.

We will try to check the working versions in the next few weeks to update the documentation in any case.
