[uilianries]

why libzmq and not zeromq? Is there any idea for zeromq as installer package? The folder name is zeromq btw.

[madebr]

My reasoning is that the name of the project is libzma: https://github.com/zeromq/libzmq/

[uilianries]

fair enough!

[danimtb]

I see vcpkg names it zeromq... we will need some consensus here @Croydon @Minimonium

[Minimonium]

There are inconsistencies in how they name their own releases on various platforms, both names are used: https://zeromq.org/download/

It's better to have the name parity in package managers - better discoverability for users as per #52

On the other hand, their target's name is libzmq so we need then to specify it as cpp_info.name[...].

[madebr]

I've renamed the package to zeromq.
The cmake script create a ZeroMQConfig.cmake file, so I use self.cpp_info.names["cmake_find_package"] = ZeroMQ.

So this means that there would be no "transparent integration" as the target name will be different, right?

[Minimonium]

@danimtb The upstream project doesn't seem to support proper targets with alias support.
It suggests using find_package(ZeroMQ) but linking to the libzmq. I think we can't model it like that right now.

[danimtb]

Ok, so I think the name is ok as is right now

@madebr I just restarted the build now. Let's wait.

I'm requesting several changes related to the test_package:

• Consume it using cmake_find_package so we realize what the name of the target is. (We will also need cmake generator and conan_basic_setup() call in order to adjust compiler flags... the toolchain should arrive sooner than later, but meanwhile, it is needed)
• The WITH_LIBSODIUM definition should be added to the cpp_info, Conan will add it to the target and apply it to the test executable

[Minimonium]

We will also need cmake generator and conan_basic_setup() call in order to adjust compiler flags

That's a bit of news for me. Could you elaborate?

Nothing new, in the conan_basic_setup() call there is a lot of magic, a lot of functions are being called that use the CONAN_XXXX variables to set all kinds of stuff. If we just use the cmake_find_package generator we can take care of everything related to the dependencies, but not to things that should affect the binaries we are generating (runtime, cppstd,...) even if those are just the test_executable.exe

[Minimonium]

It's just that I have a few test packages here without it (only with the cmake_find_package). 🙁

Thanks for the information!

[jgsogo]

Most of the time the test_package is so simple that it compiles without it, but I prefer to have it there to avoid some copy/paste issues 😄
