+# CPM
+
+CPM (CMake Package Manager) is the preferred method of managing dependencies within Eden. Documentation on adding dependencies/using CPMUtil is in the works.
+
+Notes:
+- `YUZU_USE_CPM` is set by default on MSVC and Android. Other platforms should use this if certain "required" system dependencies (e.g. OpenSSL) are broken or missing
+- `CPMUTIL_DEFAULT_SYSTEM` can be set to `OFF` to force the usage of bundled dependencies. This can marginally decrease the final package size.
+- When adding new prebuilt dependencies a la OpenSSL, SDL2, or FFmpeg, there *must* be a CMake option made available to forcefully download this bundle. See the OpenSSL implementation in the root CMakeLists for an example.
+  * This is necessary to allow for creation of fully-qualified source packs that allow for offline builds after download (some package managers and distros enforce this)

 ## One word of caution before proceeding.

 This is not the usual or preferred way to build programs on FreeBSD.
-As of writing there is no official fresh port available for eden-emu, but it is in the works.
-After it is available you can find a link to the eden-emu fresh port here and on Escarys github repo.

+The available OpenSSL port (3.0.17) is out-of-date, and using a bundled static library instead is recommended; to do so, add `-DYUZU_USE_CPM=ON` to your CMake configure command.
