Support Conan 2.0

[jmarrec]

Issue overview

Conan 2.0 has been officially released and includes a number of API breaking changes. Currently we can't build with conan 2.0

Linked issue (where most of the work will be):

• Port to conan 2.0 conan-openstudio-ruby#47

Just curious, is it possible? Since the cmake-conan hasn't supported conan 2.0 yet:

https://github.com/conan-io/cmake-conan

I am new to the project and Cmake ecosystem, maybe I am wrong.

Hi @wnykuang! Using 2.0 should be possible but it's broken as of now, so you should install the latest 1.X series which I believe is 1.59 https://pypi.org/project/conan/1.59.0/

Hi! Glad to hear from you!

Yeah, I built the project with 1.48since the script(I believe it's CMake-Conan or something) indicate.
Just curious whether it's possible to support 2.0 from ourside if CMake-Conan doesn't support it yet.

(They indicate:

Compatibility with Conan 2.0: cmake-conan is not compatible with Conan 2.0 for the moment. Once Conan 2.0 is GA the compatibility between both will be analyzed again. Also, please note that CMakeToolchain is not compatible with cmake-conan. If you need to use it, we would recommend not using cmake-conan but doing a conan install directly.
)

(I spent a while to try to build it with Conan 2.0 and figured out there is version issue)

This is a very good point.
But this isn't a strong necessity as of now, just rely on conan 1.59, I'm just logging it in an issue for later.
Cmake conan will either catchup or we'll just generate a conanfile.txt and call conan on it to match the preferred 2.0 workflow. For now, let's just focus on releasing OS sdk 3.6 :)

FYI there's a develop2 branch with experimental support on https://github.com/conan-io/cmake-conan/tree/develop2

Interesting! I didn't notice it. Thanks for the heads-up, let me take a look!

@jmarrec @kbenne Seems like this was addressed by #5137. Close the issue?
