+# AddJsonPackage
+
+In each directory that utilizes `CPMUtil`, there must be a `cpmfile.json` that defines dependencies in a similar manner to the individual calls.
+
+The cpmfile is an object of objects, with each sub-object being named according to the package's identifier, e.g. `openssl`, which can then be fetched with `AddJsonPackage(<identifier>)`. Options are designed to map closely to the argument names, and are always strings unless otherwise specified.
+<!-- TOC -->
+- [Options](#options)
+- [Examples](#examples)
+<!-- /TOC -->
+
+## Options
+
+- `package` -> `NAME` (`PACKAGE` for CI), defaults to the object key
+- `repo` -> `REPO`
+- `version` -> `VERSION`
+- `ci` (bool)
+
+If `ci` is `false`:
+
+- `hash` -> `HASH`
+- `hash_suffix` -> `HASH_SUFFIX`
+- `sha` -> `SHA`
+- `key` -> `KEY`
+- `tag` -> `TAG`
+  * If the tag contains `%VERSION%`, that part will be replaced by the `git_version`, OR `version` if `git_version` is not specified
+- `url` -> `URL`
+- `artifact` -> `ARTIFACT`
+  * If the artifact contains `%VERSION%`, that part will be replaced by the `git_version`, OR `version` if `git_version` is not specified
+  * If the artifact contains `%TAG%`, that part will be replaced by the `tag` (with its replacement already done)
+- `git_version` -> `GIT_VERSION`
+- `git_host` -> `GIT_HOST`
+- `source_subdir` -> `SOURCE_SUBDIR`
+- `bundled` -> `BUNDLED_PACKAGE`
+- `find_args` -> `FIND_PACKAGE_ARGUMENTS`
+- `download_only` -> `DOWNLOAD_ONLY`
+- `patches` -> `PATCHES` (array)
+- `options` -> `OPTIONS` (array)
+- `skip_updates`: Tells `check-updates.sh` to not check for new updates on this package.
+
+Other arguments aren't currently supported. If you wish to add them, see the `AddJsonPackage` function in `CMakeModules/CPMUtil.cmake`.
+
+If `ci` is `true`:
+
+- `name` -> `NAME`, defaults to the object key
+- `extension` -> `EXTENSION`, defaults to `tar.zst`
+- `min_version` -> `MIN_VERSION`
+- `extension` -> `EXTENSION`
+- `disabled_platforms` -> `DISABLED_PLATFORMS` (array)
+
+## Examples
+
+In order: OpenSSL CI, Boost (tag + artifact), Opus (options + find_args), discord-rpc (sha + options + patches).

+<!-- /TOC -->
+
+## Identification/Fetching
+
+- `NAME` (required): The package name (must be the same as the `find_package` name if applicable)
+- `VERSION`: The minimum version of this package that can be used on the system
+- `GIT_VERSION`: The "version" found within git
+- `URL`: The URL to fetch.
+- `REPO`: The repo to use (`owner/repo`).
+- `GIT_HOST`: The Git host to use
+  * Defaults to `github.com`. Do not include the protocol, as HTTPS is enforced.
+- `TAG`: The tag to fetch, if applicable.
+- `ARTIFACT`: The name of the artifact, if applicable.
+- `SHA`: Commit sha to fetch, if applicable.
+- `BRANCH`: Branch to fetch, if applicable.
+
+The following configurations are supported, in descending order of precedence:
+
+- `URL`: Bare URL download, useful for custom artifacts
+  * If this is set, `GIT_URL` or `REPO` should be set to allow the dependency viewer to link to the project's Git repository.
+  * If this is NOT set, `REPO` must be defined.
+- `REPO + TAG + ARTIFACT`: GitHub release artifact
+  * The final download URL will be `https://github.com/${REPO}/releases/download/${TAG}/${ARTIFACT}`
+  * Useful for prebuilt libraries and prefetched archives
+- `REPO + TAG`: GitHub tag archive
+  * The final download URL will be `https://github.com/${REPO}/archive/refs/tags/${TAG}.tar.gz`
+  * Useful for pinning to a specific tag, better for build identification
+- `REPO + SHA`: GitHub commit archive
+  * The final download URL will be `https://github.com/${REPO}/archive/${SHA}.zip`
+  * Useful for pinning to a specific commit
+- `REPO + BRANCH`: GitHub branch archive
+  * The final download URL will be `https://github.com/${REPO}/archive/refs/heads/${BRANCH}.zip`
+  * Generally not recommended unless the branch is frozen
+- `REPO`: GitHub master archive
+  * The final download URL will be `https://github.com/${REPO}/archive/refs/heads/master.zip`
+  * Generally not recommended unless the project is dead
+
+## Hashing
+
+Hashing is used for verifying downloads. It's highly recommended to use these.
+
+- `HASH_ALGO` (default `SHA512`): Hash algorithm to use
+
+Hashing strategies, descending order of precedence:
+
+- `HASH`: Bare hash verification, useful for static downloads e.g. commit archives
+- `HASH_SUFFIX`: Download the hash as `${DOWNLOAD_URL}.${HASH_SUFFIX}`
+  * The downloaded hash *must* match the hash algorithm and contain nothing but the hash; no filenames or extra content.
+- `HASH_URL`: Download the hash from a separate URL
+
+## Other Options
+
+- `KEY`: Custom cache key to use (stored as `.cache/cpm/${packagename_lower}/${key}`)
+  * Default is based on, in descending order of precedence:
+    - First 4 characters of the sha
+    - `GIT_VERSION`
+    - Tag
+    - `VERSION`
+    - Otherwise, CPM defaults will be used. This is not recommended as it doesn't produce reproducible caches
+- `DOWNLOAD_ONLY`: Whether or not to configure the downloaded package via CMake
+  * Useful to turn `OFF` if the project doesn't use CMake
+- `SOURCE_SUBDIR`: Subdirectory of the project containing a CMakeLists.txt file
+- `FIND_PACKAGE_ARGUMENTS`: Arguments to pass to the `find_package` call
+- `BUNDLED_PACKAGE`: Set to `ON` to default to the bundled package
+- `FORCE_BUNDLED_PACKAGE`: Set to `ON` to force the usage of the bundled package, regardless of CPMUTIL_FORCE_SYSTEM or `<package>_FORCE_SYSTEM`
+- `OPTIONS`: Options to pass to the configuration of the package
+- `PATCHES`: Patches to apply to the package, stored in `.patch/${packagename_lower}/0001-patch-name.patch` and so on
+- Other arguments can be passed to CPM as well
+
+## Extra Variables
+
+For each added package, users may additionally force usage of the system/bundled package.
+
+- `${package}_FORCE_SYSTEM`: Require the package to be installed on the system
+- `${package}_FORCE_BUNDLED`: Force the package to be fetched and use the bundled version
+
+## System/Bundled Packages
+
+Descending order of precedence:
+- If `${package}_FORCE_SYSTEM` is true, requires the package to be on the system
+- If `${package}_FORCE_BUNDLED` is true, forcefully uses the bundled package
+- If `CPMUTIL_FORCE_SYSTEM` is true, requires the package to be on the system
+- If `CPMUTIL_FORCE_BUNDLED` is true, forcefully uses the bundled package
+- If the `BUNDLED_PACKAGE` argument is true, forcefully uses the bundled package
+- Otherwise, CPM will search for the package first, and if not found, will use the bundled package
+
+## Identification
+
+All dependencies must be identifiable in some way for usage in the dependency viewer. Lists are provided in descending order of precedence.
+
+URLs:
+
+- `GIT_URL`
+- `REPO` as a Git repository
+  * You may optionally specify `GIT_HOST` to use a custom host, e.g. `GIT_HOST git.crueter.xyz`. Note that the git host MUST be GitHub-like in its artifact/archive downloads, e.g. Forgejo
+  * If `GIT_HOST` is unspecified, defaults to `github.com`
+- `URL`
+
+Versions (bundled):
+
+- `SHA`
+- `GIT_VERSION`
+- `VERSION`
+- `TAG`
+- "unknown"
+
+If the package is a system package, AddPackage will attempt to determine the package version and append ` (system)` to the identifier. Otherwise, it will be marked as `unknown (system)`

+# CPMUtil
+
+CPMUtil is a wrapper around CPM that aims to reduce boilerplate and add useful utility functions to make dependency management a piece of cake.
+
+Global Options:
+
+- `CPMUTIL_FORCE_SYSTEM` (default `OFF`): Require all CPM dependencies to use system packages. NOT RECOMMENDED!
+  * You may optionally override this (section)
+- `CPMUTIL_FORCE_BUNDLED` (default `ON` on MSVC and Android, `OFF` elsewhere): Require all CPM dependencies to use bundled packages.
+
+You are highly encouraged to read AddPackage first, even if you plan to only interact with CPMUtil via `AddJsonPackage`.
+
+<!-- TOC -->
+- [AddPackage](#addpackage)
+- [AddCIPackage](#addcipackage)
+- [AddJsonPackage](#addjsonpackage)
+- [Lists](#lists)
+<!-- /TOC -->
+
+## AddPackage
+
+The core of CPMUtil is the [`AddPackage`](./AddPackage.md) function. [`AddPackage`](./AddPackage.md) itself is fully CMake-based, and largely serves as an interface between CPM and the rest of CPMUtil.
+
+## AddCIPackage
+
+[`AddCIPackage`](./AddCIPackage.md) adds a package that follows [crueter's CI repository spec](https://github.com/crueter-ci).
+
+## AddJsonPackage
+
+[`AddJsonPackage`](./AddJsonPackage.md) is the recommended method of usage for CPMUtil.
+
+## Lists
+
+CPMUtil will create three lists of dependencies where `AddPackage` or similar was used. Each is in order of addition.
+
+- `CPM_PACKAGE_NAMES`: The names of packages included by CPMUtil
+- `CPM_PACKAGE_URLS`: The URLs to project/repo pages of packages
+- `CPM_PACKAGE_SHAS`: Short version identifiers for each package
+    * If the package was included as a system package, ` (system)` is appended thereafter
+    * Packages whose versions can't be deduced will be left as `unknown`.
+
+For an example of how this might be implemented in an application, see Eden's implementation:
+
+- [`dep_hashes.h.in`](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/src/dep_hashes.h.in)
+- [`GenerateDepHashes.cmake`](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/CMakeModules/GenerateDepHashes.cmake)
+- [`deps_dialog.cpp`](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/src/yuzu/deps_dialog.cpp)
