Add library to toolchain?

I am trying to build a package that requieres libvlc, if I add it to the toolchain manually (on the build directory) it builds fine, but if a do a "clean" I have to do all the steps again manually, is there a way to add it to to toolchain permanently?

Thanks!

You need to make a proper package libvlc and add it as dependency for some other. Like everything in LE is build.

Thank you, I added VLC and it worked
