I am using a Linux Ubuntu 18.04 and have downloaded and run the sample programs from the dji OSDK github.
Now I am trying to create a new sample program and am having trouble linking up the files.



I have attatched my CMakeLists.txt file. Below is the error message

What is causing the undefined reference error? Are there any other files I should include?

Thanks!

I ended up changing my cmake file to look more like this one: https://stackoverflow.com/questions/67429895/how-to-create-cmakelist-txt-for-onboard-sdk-project-on-debian-10
