How to cross-build c++ freeOpcUa in Ubuntu to use for embedded ARM?

[QHWG67]

I would like to use the arm-linux-gcc complier to build the whole c++ project in Ubuntu OS of VirtualBox, use the results(.so etc) in embedded device. So how should I update the CMakeLists.txt file to use CMake to build them instead of using IDE? Many thanks!

One of the options is VisualGDB: https://visualgdb.com/ With it, you can use Visual Studio (community edition) as main IDE, and from there use Ubuntu VM to build binaries for ARM target, then run and debug on your embedded device

This is a CMake question and not a freeopcua question. I recommend reading about cross-compiling with CMake and how to use Toolchain files. If you're a Docker fan, this can help too: https://github.com/dockcross/dockcross

And the reason I say with such confidence that it's not a freeopcua question is because I've built freeopcua for armv7hf without any problems or tweeks to the CMake scripts other than providing a toolchain file on the command line. Works great :)
