Please support catch2 3.x

[hosiet]

The current source code needs catch2 2.x to do the tests. With catch2 upstream shifting to the development of v3.x series (currently v3.6.0), please consider updating your source code structure to support catch2 3.x.

Hey @hosiet feel free to open a PR against the dev branch.

I have patch for the code and CMakeLists.txt available and I can provide them. However, the main issue is that Hunter only supports Catch 2.x and there is no sign of supporting 3.x on their side.

Please let me know what would be the best way to proceed. I am attaching the patches here in case anyone need them.
