G++/GCC: how to make your app tell OS to download libs it needs into system?

So for example I am creating some app that uses boost or openCV and on my developer machine all that is installed so app compiles without any problem. But I wonder how to make app tell OS to download libs I use on first run? Is it possi开发者_JS百科ble? (sorry - I am linux noob)

This is what package managers are for. What you do is you compile your project, and then you build a package (e.g. .deb or .rpm), using the appropriate tools. While doing so, you can specify where the various files in your package should go, but also which other packages your package relies on. These are known as "dependencies", and package managers like apt and rpm are pretty good at resolving them.

Here's the official debian guide to making packages to give you an idea: http://www.debian.org/doc/maint-guide/

Alternatively, you can just distribute your program as-is and list the dependencies in the install instructions; users will then have to manually install them through their package manager before running your program.
