矩阵库（附带一些常用函数，随机数生成等） 4. Tencent/rapidjson - 单纯的 JSON 库，甚至没依赖 STL（可定制性高，工程美学经典） 5. ericniebler/range-v3 - C++20 ranges 库就是受到他启发（完全是头文件组成） 6. fmtlib/fmt - 格式化库，提供 std::format 的替代品（需要 -DFMT_HEADER_ONLY） 格式化库，提供 std::format 的替代品 2. gabime/spdlog - 能适配控制台，安卓等多后端的日志库 CMakeLists.txt 3. ericniebler/range-v3 - C++20 ranges 库就是受到他启发 1 cmake_minimum_required(VERSION 3.12) 4. g-truc/glm - 模仿 GLSL 语法的数学矢量 PUBLIC TBB::tbb TBB::tbbmalloc) ## 第三方库 - 常用 package 列表 1. fmt::fmt 2. spdlog::spdlog 3. range-v3::range-v3 4.
