Summary: Update Eden's top-level CMakeLists.txt file to build the Rust datapack libraries. Previously these were built by invoking CMake separately inside th `eden/scm` subdirectory. Now that the code has been combined into a single location we can use a single CMake invocation to drive the build of both these components. The old code did not build the Rust datapack code on Windows, and this diff does not change that behavior. I'm not aware of any reason to skip building this on Windows, so I plan to enable building this code on Windows in a subsequent diff.

EdenFS is a FUSE virtual filesystem for source control repositories.
EdenFS speeds up operations in large repositories by only populating working
directory files on demand, as they are accessed. This makes operations like
checkout much faster, in exchange for a small performance hit when first
accessing new files. This is quite beneficial in large repositories where
developers often only work with a small subset of the repository at a time.
EdenFS has similar performance advantages to using sparse checkouts, but a much better user experience. Unlike with sparse checkouts, EdenFS does not require manually curating the list of files to check out, and users can transparently access any file without needing to update the profile.
EdenFS also keeps track of which files have been modified, allowing very
efficient status queries that do not need to scan the working directory.
The filesystem monitoring tool Watchman
also integrates with EdenFS, allowing it to more efficiently track updates to
the filesystem.
Building EdenFS
EdenFS currently only builds on Linux. We have primarily tested building it on Ubuntu 18.04.
TL;DR
[eden]$ ./getdeps.py --system-deps
[eden]$ mkdir _build && cd _build
[eden/_build]$ cmake ..
[eden/_build]$ make
Dependencies
EdenFS depends on several other third-party projects. Some of these are commonly available as part of most Linux distributions, while others need to be downloaded and built from GitHub.
The getdeps.py script can be used to help download and build EdenFS's
dependencies.
Operating System Dependencies
Running getdeps.py with --system-deps will make it install third-party
dependencies available from your operating system's package management system.
Without this argument it assumes you already have correct OS dependencies
installed, and it only updates and builds dependencies that must be compiled
from source.
GitHub Dependencies
By default getdeps.py will check out third-party dependencies into the
eden/external/ directory, then build and install them into
eden/external/install/
If repositories for some of the dependencies are already present in
eden/external/ getdeps.py does not automatically fetch the latest upstream
changes from GitHub. You can explicitly run ./getdeps.py --update if you
want it to fetch the latest updates for each dependency and rebuild them from
scratch.
