Create a cmake export target #31

Closed gillins closed 1 year ago

And use it when building the Python bindings.

Should make it easier for cmake projects to link against libkea.

Given the project name and the Kealib target name, it might have more sense to create Kealib CMake package with a Kealib::Kealib target. Or is this something which would be still considered worth adopting?

Agreed. Perhaps we can change this for 1.6.0 (I'm hoping to push out 1.5.3 soon)? 1.6.0 will have some larger changes so that would be a good time to rename.

It might be possible to have both in 1.5.3, and then remove the other one in 1.6.0.

That's a good plan. Are you happy to create a PR for this?

dg0yt commented 11 months ago

I can do that. With your indication of acceptance, I can test this in the vcpkg port as part of a fix which includes a usage synopsis. And I would prefer to never document anything else ;-)

However, to minimize impact, I suggest two steps:

For 1.5.3: Leave export mostly as is, and generate the Kealib config/namespace as a separate trivial config file / interface target. This will leave all existing targets where they are now.
for 1.6.0: Get rid of all libkea config/namespace stuff, and move to Kealib-only.

Sounds good. We'd also have to submit something to GDAL that looks for the new target, but can also try the old one (for people still on older kealib). Not sure if this is possible?

This is where I come from: https://github.com/microsoft/vcpkg/pull/35437/files Once Kealib's CMake config is stable, we can look at a GDAL PR.
