Conan Scm [repack]

conan build . --aggregate-scm

In a conanfile.py , the SCM feature is typically defined through the scm attribute:

Capturing Git scm information — conan 2.27.0 documentation

from conans import ConanFile class MyPackage(ConanFile): scm = { "type": "git", "url": "auto", # Automatically captures the remote URL "revision": "auto", # Automatically captures the commit hash "subfolder": "src" # Destination for cloned sources } Use code with caution. : Specifies the VCS, commonly git or svn . conan scm

The Citadel fractured. Projects were abandoned. Builds took weeks, as mages traveled on foot between keeps, carrying handwritten manifests of dependencies. They would beg, borrow, or fight for a single library file. The term "DLL Hell" was not a metaphor—it was the lower dungeons, where failed builds were eternally tormented by missing symbols and version mismatches.

And when a new mage would ask, “How do we link Poco against OpenSSL without breaking everything?”, the elders would smile and point to the statue in the center of the hall—a steel-gray warrior with a recipe for a sword. conan build

It allows users to download and use pre-compiled binaries even if they don't have access to the underlying source repository. Access is only required if they need to build from source.

Once a package is created, it is linked to that specific point in time in your repository.

The mages laughed nervously. “Friend,” said one, “we have all the problems. The Math Keep won’t share their Eigen library. The Crypto Crypt has locked their SSL inside a vault that only accepts ‘GCC 5.4’ as a password. And the RenderKeep—their old OpenGL library is fighting with the new Vulkan shader.” They would beg, borrow, or fight for a single library file

They run:

Allow a recipe to declare that its source code is located relative to the parent directory, without needing to clone it again.

Eliminate version mismatches between team members.

The final battle was at the Monorepo—a single, colossal fortress where all the Citadel’s code was supposed to live in harmony. Instead, it was a nightmare of tangled #include paths, hacked CMake modules, and a build script that took three days to run.
