build: simplify find modules With this patch I've deleted a few find modules that are now unused since the vcpkg transition, as the CMake code now forces CONFIG mode for Catch2, fmt and nlohmann_json. I've then simplified the lz4, opus, and zstd modules by exclusively using pkg-config. They were using it already, but were ignoring the result. Also, I believe that manually looking for libraries was required for Conan to work, and it is thus not needed anymore. Lastly, I believe that there is no platform that ships these system libs without pkg-config/pkgconf, so requiring it should be fine. 2022-07-28 09:44:52 -05:00			`# SPDX-FileCopyrightText: 2022 yuzu Emulator Project`
chore: make yuzu REUSE compliant [REUSE] is a specification that aims at making file copyright information consistent, so that it can be both human and machine readable. It basically requires that all files have a header containing copyright and licensing information. When this isn't possible, like when dealing with binary assets, generated files or embedded third-party dependencies, it is permitted to insert copyright information in the `.reuse/dep5` file. Oh, and it also requires that all the licenses used in the project are present in the `LICENSES` folder, that's why the diff is so huge. This can be done automatically with `reuse download --all`. The `reuse` tool also contains a handy subcommand that analyzes the project and tells whether or not the project is (still) compliant, `reuse lint`. Following REUSE has a few advantages over the current approach: - Copyright information is easy to access for users / downstream - Files like `dist/license.md` do not need to exist anymore, as `.reuse/dep5` is used instead - `reuse lint` makes it easy to ensure that copyright information of files like binary assets / images is always accurate and up to date To add copyright information of files that didn't have it I looked up who committed what and when, for each file. As yuzu contributors do not have to sign a CLA or similar I couldn't assume that copyright ownership was of the "yuzu Emulator Project", so I used the name and/or email of the commit author instead.

build: tweak the find modules even more As described in https://github.com/yuzu-emu/yuzu/pull/9395#discussion_r1047456172 checking for PKG_CONFIG_FOUND before calling pkg_search_module() is unneeded, and some find modules (like FindFFmpeg.cmake) don't do this already. Consequently, this patch removes these checks. 2022-12-14 02:30:31 -06:00			`pkg_search_module(ZSTD QUIET IMPORTED_TARGET libzstd)`
