Implement the packaging and out of the tree build system

[nohal]

J-E...
I'm converting all the plugins to the new unified packaging system. Should work without any problems on all the platforms.

I'm reluctant to #include "ocpn_plugin.h" in every project.
I'd rather create a opencpn-devel package that'd install it under /usr/include/ocpn_plugin.h and use that one.
I know it'd not be portable for windows but we could come with an option --with-ocpn-plugin=/path/to/ocpn_plugin.h

Thanks

We may also include shared cmake files

But how do you want to handle the (normal) situation when you will work on plugins with different API compatibility levels? Not easily doable using the dev package even on Linux...
Not including ocpn_plugin.h will at the end have only one effect: Total confusion.

[SethDart]

What do you mean with "plugins with different API compatibility levels"?
The same plugin behaving differently for different API version?
Or the plugin built for different API version?

For the latter, you can do it with --with-ocpn-plugin=/path/to/ocpn_plugin_api_vXXX.h
If you're packaging it, you can require a different opencpn-devel version in your spec file and the builder will do the job.

While I can imagine several workarounds to make it work on Linux. I can't imagine anybody on Windows or OS X being able to follow the logic, really. For example on Windows, you can't even link the plugin without the right combination of the header and opencpn.lib, unfortunately. I also don't have capacity to maintain the dev packages on all the platforms and am not aware of anybody who would.
But feel free to prove me wrong, of course - If it works and somebody will maintain it, it is no doubt the cleanest solution.

[SethDart]

Don't get me wrong, I'm trying to find the best solution.

If I follow your logic, we should also include opencpn.lib or the plugin may not be built on Windows for this particular header file.

Please let's follow this on the forum to see how it goes:
