Sorry for my poor English.

Some cross-platform C++ libraries are useful for game developing, e.g., Eigen, Skia, OpenCV, Tensor Flow. I am not sure whether they are really limited to officially stated supported platforms (desktop and mobile only) without supports on game console and web platforms. Thank you. I just want to conform it. Let me know whether those libraries are indeed very limited in terms of cross-platform portability for game developing.

    \$\begingroup\$ Is there a particular task you need to do that you don't find supported out of the box in Unity? If so, asking "How can I achieve Feature X in a cross platform way?" might help focus answers on more constructive solutions that actually move you towards your goal. With your question currently as broad as it is, I think the only answer that covers all the cases you've described is "it depends on the library" — something you probably already know from your research so far. What can we help you solve that will help you move closer to completing your game? \$\endgroup\$ – DMGregory Oct 3 '18 at 12:07
  • \$\begingroup\$ You seem very focused on C++ libraries. While you can write native C++ plug-ins for Unity, typically C# is what you code/script your game with. \$\endgroup\$ – Pikalek Oct 3 '18 at 13:41
  • \$\begingroup\$ This still falls under the "what technology to use", as "does library X support feature Y" is used just for that (without mentioning that these are not "time agnostic", and can be answered by yes or no). \$\endgroup\$ – Vaillancourt Oct 4 '18 at 0:05
  • \$\begingroup\$ Thanks. I don't know how to properly rephrase my original question. I try to simplify my question as this question \$\endgroup\$ – Air Kuma Oct 4 '18 at 1:33
