Build from source (against older version of libopencv) #15

Closed cornop closed 1 year ago

cornop commented 1 year ago

What is the requested feature? Describe what it is and what it's supposed to accomplish.

I would like to build this library from source, i.e. using a provided makefile or similar.

Why do you want this feature? Describe why it's needed, what problems it solves. If it is related to an issue, reference it here.

I'm on a distribution (Debian stable) that doesn't provide libopencv 4.6 yet. Building from source would enable me to build against my distribution's version of libopencv.

For reference, loading the plugin fails with:

Hi, this is currently in the works!

The source files now come with accompanying cmake for compilation. You can find some basic instructions can be found here.

There were major architectural changes as part of adding cmake, so be aware that the project may not be as stable as the latest release. I would recommend compiling the modular branch instead of main.

Let me know if you run into any issues!
