This is a way to cache the camera defintion files inside the library.
It turned out rather tedious to do the embedding ourselves. Therefore, we resort to using a helper repo for this. I found this here: https://stackoverflow.com/questions/4864866#answer-19180226
The Windows build failed with: CUSTOMBUILD : error : Resource file "/C:/dronecode_sdk/plugins/camera/camera_definition_files/e90.xml" cannot be open. I gave up at that point.
In order to build for e.g. iOS we need to re-use the cpp_rsc binary which is built for the build host by the `default` build.

So Yuneec MAVLink camera doesn't supply the camera definition file URL - as per the MAVLink Camera API spec? |
No, they do supply it but the problem is that the file is not accessible currently through the MFi transport layer (mavlink is transmitted but no http yet), so this is an interim workaround. |
This should use the default binary for cross-compilation.

I don't get where that is used :/

I see. And add_resource and link_resource_file come from cpp_rsc as well.

Embed camera definition files for Yuneec camera
This is an interim workaround where the camera definition xml files are embedded in the library.
The tool to embed the xml files is cpp_rsc.
