Description

This PR brings a minimal Conan recipe to Catch project. It just copy single_header to Conan package.
To solve the tests, I just copied BDDTests and TrickyTest to validate Catch package.

In the future we could improve many other things (build all Catch project by Conan), but is a different feature.

Closes #926

I don't think so much testing for the package is necessary. With just a very minimal test inside test_package to ensure the package is correctly created is more than enough. Please @uilianries simplify, thanks!!

[uilianries]

@memsharded Done! I changed to a simple test (just 10 lines)

What is the conanfile.py in test_package for? It has a hard coded version number that never gets updated - is that intended?

[memsharded]

The test_package is a folder containing a consumer project. It is used to make sure that packages are properly created, headers are packaged, libs are there... It is automatically used by the conan test_package command that manages to export the package recipe (the root conanfile.py) into the local cache, build the package, and consume the package from the test_package project to ensure everything is OK.

About the version in test_package/conanfile.py -> requires, good catch ;)
Yes, @uilianries, that version should be also changed by the updateConan, or maybe we can just wait. Next release will get rid of it, and the consumer test_package will not have to require the tested package explicitly.

@memsharded Thanks for the comments!

@philsquared I can change test_package/conanfile.py by updateConan in this PR, if you wish.

[philsquared]

Yes please - then I think we can get this in

[uilianries]

@philsquared Done!

[philsquared]

That was quick! Thanks. I'll probably take a look tomorrow

[philsquared]

Thanks - I've now merged this.
In fact I did it in two parts, as I'd already merged, and tweaked, the version before that last update yesterday - so I just cherry-picked the last update on top of that.
That seems to have prevented GitHub from recognising that the whole PR has been merged so I'll close it manually here.

@philsquared and @memsharded Thanks!
