Recipe taken from https://github.com/bincrafters/conan-nghttp2

• I've read the guidelines for contributing.
• I've followed the PEP8 style guides for Python code in the recipes.
• I've used the latest Conan client version.
• I've tried at least one configuration locally with the
  conan-center hook activated.

Where are these pkg-config coming from? Should this recipe us the pkg_config generator for this with_app option?

[jgsogo]

It looks like that the name for the c-ares library should be libcares so Conan generates the proper .pc file. Or we should use the components feature to give it a different name.

[SSE4]

we already have cppinfo.name, that should be enough, right?

[jgsogo]

Anyway, this is not an issue of this recipe, but the c-ares one

@jgsogo What was the motivation for this? The project calls itself nghttp2?

[jgsogo]

I can't remember right now 😓 Several options come to my mind: Windows or something related to libcurl consuming this recipe (https://github.com/jgsogo/conan-center-index/tree/recipe/libcurl/recipes/libcurl). Tomorrow I will have a look at libcurl and hope I will realize about it.
