How to add a package to Cygwin from an external folder?

How to add a package to Cygwin from an external folder?

[Alessandro Francesconi]

I'm new on Cygwin environment and I'm wondering if it's possible to "link" a package that's already stored on my hard-drive, but it's out from the default Cygwin folder. I'll be more precise:
My Cygwin environment is in C:\dev\cygwin, I need to manually install a particular version of a package that's not available in the default remote repository, for example libgimp2.0-dev (version 2.6.0)

But I've already got it from the net! I've put it in C:\dev\gimp-dev (NOTE: I'm trying to give some "modularity" to my Cygwin installation, that's the reason why I didn't put it directly inside Cygwin folder, I would like to replace gimp-dev with a newer version whenever I want).

So, now I have a manually downloaded package in a folder that's OUTSIDE the Cygwin environment. In this situation, when I want to compile something using that package, gcc returns a linker error because (according to Cygwin) the package libgimp2.0-dev doesn't exist.

How can I make it visible to Cygwin without cut & paste it inside C:\dev\cygwin? Should I add some environment variable? Thank you!

P.S.: btw, I’ve posted the same question on Stackoverflow - sorry for the repetition - so if you want you can reply from there: http://stackoverflow.com/questions/19209265/add-a-package-to-cygwin-from-an-external-folder

Do you want to actually install it or to show it to you on setup.exe but do nothing?

You can access paths that aren't under the Cygwin root directory
(C:\dev\cygiwn in your case) using the '/cygdrive' path from Cygwin shells.
See the section about cygdrive in the Users Guide for more details:
