Some pure conan options, there's a 2.0 super early developer preview for https://github.com/conan-io/cmake-conan/tree/develop2

https://github.com/conan-io/cmake-conan/tree/develop2 might interest you :) we love feedback

I totally agree with you. Have a look at the new cmake-conan integration using Dependency Provider in the develop2 branch : https://github.com/conan-io/cmake-conan/tree/develop2

I've always used conan together with the conan cmake module

using conan from within cmake you can use this https://github.com/conan-io/cmake-conan, or just write your own execute process way of calling it . https://cmake.org/cmake/help/latest/command/execute_process.html

See https://github.com/conan-io/cmake-conan for a neat wrapper that I use in almost all my projects

I always wanted to try to use cmake-conan so I could let Conan grab all packages but have a neat cmake script being in charge of what gets built when. Also, this would allow me to easily switch between CMake fetchcontent and Conan packages that may or may not be stashed automatically on a local Artifactory server. Secondly, since now all build requirements are stashed on a server and binary reproducible, you could concider adding icecream and ccache into the mix. (Try running a node one of your buildservers for massive speadups with icecream) This however does require a reproducible build environment (by configure script) which conan again is really good in.

Conan is a package manager for C/C++. See: https://conan.io/.

The way it works is that you can provide "recipes", which are Python scripts, that automate the process of collecting source code (usually from a remote Git repository, or a remote source tarball), patching it, making its dependencies and transitive dependencies available, building for specific platform and architecture (via any number of build systems), then packaging up and serving binaries. There's a lot of complexity involved.

Here are the two recipes I mentioned:

libcurl: https://github.com/conan-io/conan-center-index/blob/master/r...

OpenSSL v3: https://github.com/conan-io/conan-center-index/blob/master/r...

Now, for the sake of this thread I want to highlight three things here:

- Conan recipes are usually made by people unaffiliated with the libraries they're packaging;

- The recipes are fully Turing-complete, do a lot of work, have their own bugs - therefore they should really be treated as software comonents themselves, for the purpose of OSS clearing/supply chain verification, except as far as I know, nobody does it;

- The recipes can, and do, patch source code and build scripts. There's supporting infrastruture for this built into Conan, and of course one can also do it by brute-force search and replace. See e.g. ZLib recipe that does it both at the same time:

https://github.com/conan-io/conan-center-index/blob/7b0ac710... -- `_patch_sources` does both direct search-and-replace in source files, and applies the patches from https://github.com/conan-io/conan-center-index/tree/master/r....

Now, good luck keeping track of what's going on there.

Just checkout ConanCenter https://conan.io/center it's free.

https://github.com/conan-io/conan-center-index there's 200+ PR that need reviewing :) we add community reviewers fairly often

As for ffmpeg it was last updated 10 days ago https://github.com/conan-io/conan-center-index/commits/master/recipes/ffmpeg/all :)

This is a more complicated recipe https://github.com/conan-io/conan-center-index/blob/master/recipes/pcapplusplus/all/conanfile.py

You can use the Conan package manager with prebuilt binaries/libraries

https://conan.io/center

It's available in Conan too https://github.com/conan-io/conan-center-index/tree/master/recipes/crowcpp-crow though it's not well maintained so no promises if it's working

You need something like https://conan.io/center/ to install the dependencies. You're lucky because it works well with CMake.

This post on github contains a list of packages supported by conan 2.0, its also kept up to date https://github.com/conan-io/conan-center-index/discussions/16196

Use a package manager: https://vcpkg.link/ https://conan.io/center/
