Sometimes, it is necessary to create packages from existing binaries, like binaries from third parties, or previously built by another process or team not using conan, so building from sources is not wanted. You would want to package local files in two situations:. For this use case, it is possible to use conan export-pkg command directly.
A conan recipe is still needed, in this case it will be very simple, just the meta information of the package. A basic recipe can be created with the conan new command:. This method can be further customized to provide other build flags typically conditioned to the settings. This package recipe can be also extended to provide support for more configurations for example, adding options: In this case, having a complete conan recipe, with the detailed retrieval of the binaries could be the preferred way, because it has better reproducibility, and the original binaries might be traced.
Such a recipe would be like:. Typically, pre-compiled binaries come for different configurations, so the only task that the build method has to implement is to map the settings to the different URLs. Upgrading to conan 1. You would want to package local files in two situations: When it is not possible to build the packages from sources only pre-built binaries available. When you are developing your package locally and want to export the built artifacts to the local cache.
This way you can keep your build cache if you are using an IDE or calling locally to the conan build command. A basic recipe can be created with the conan new command: Such a recipe would be like: Note This is a normal conan package, even if the binaries are being retrieved from somewhere. The recommended approach is using conan create , and have a small consuming project besides the above recipe, to test locally, then upload the conan package with the binaries to the conan remote with conan upload.
The same building policies apply. Having a recipe will fail if no conan packages are created, and the --build argument is not defined. If they are external internet , it could be better to create the packages and store them in your own conan server, so builds do not rely on the third party URL being available.
