#546 Could we have a --without-jasper config option?

[Andrew Janke]

When building GraphicsMagick, it looks like it will detect and opportunistically link to the Jasper library. Unlike gslib, webp, ttf, and other libraries, though, there doesn't seem to be a configure option to disable this. Could one be added? This would support the case of building GraphicsMagick on a host that may have Jasper installed, but for use on another host that doesn't have Jasper installed, or to have GM continue to work once Jasper is uninstalled.

There's an actual case for this: when building GraphicsMagick for use with a package manager, like a Linux distro or Mac Homebrew (which is what I'm working on), you might want to build GraphicsMagick without a dependency on Jasper, so you don't have to declare the dependency in the package manager.

Use the --without-jp2 configuration option.
