+
+Drogon supports cross-compilation, you should define the `CMAKE_SYSTEM_NAME` in toolchain file, for example:
+    
+```cmake
+set(CMAKE_SYSTEM_NAME Linux)
+set(CMAKE_SYSTEM_PROCESSOR arm)

+
+You can disable building options for examples and drogon_ctl by settings `BUILD_EXAMPLES` and `BUILD_CTL` to `OFF` in the toolchain file.
+
+## Building options
+
+Drogon provides some building options, you can enable or disable them by setting the corresponding variables to `ON` or `OFF` in the cmake command line, cmake file etc...

+Drogon 是一個跨平台框架，支援 Linux、macOS、FreeBSD/OpenBSD、HaikuOS 和 Windows。主要特點如下：
+
+* 網路層使用基於 epoll（macOS/FreeBSD 下是 kqueue）的非阻塞 IO 框架，提供高並行、高效能的網路 IO。詳細請見 [TFB Tests Results](https://www.techempower.com/benchmarks/#section=data-r19&hw=ph&test=composite)；
+* 完全非同步的程式撰寫邏輯；
+* 支援 HTTP 1.0/1.1（伺服器端和用戶端）；
+* 基於樣板（template）實作的簡單反射機制，使主程式框架、控制器（controller）和視圖（view）完全解耦；
+* 支援 cookies 和內建的 session；
+* 支援後端算繪，將控制器產生的資料交給視圖產生 HTML 頁面，視圖由 CSP 樣板檔案描述，透過 CSP 標籤將 C++ 程式碼嵌入 HTML 頁面，由 drogon 的命令列工具在編譯階段自動產生 C++ 程式碼並編譯；
+* 支援執行期的視圖頁面動態載入（動態編譯和載入 so 檔案）；
+* 非常方便靈活的路徑（path）到控制器處理函式（handler）的對應方案；
+* 支援過濾器（filter）鏈，方便在控制器之前執行統一的邏輯（如登入驗證、HTTP Method 限制驗證等）；
+* 支援 HTTPS（基於 OpenSSL）；
+* 支援 WebSocket（伺服器端和用戶端）；
+* 支援 JSON 格式的請求和回應，方便開發 RESTful API；
+* 支援檔案下載和上傳，支援 `sendfile` 系統呼叫；
+* 支援 Gzip/Brotli 壓縮傳輸；
+* 支援 pipelining；
+* 提供輕量的命令列工具 `drogon_ctl`，幫助簡化各種類別的建立和視圖程式碼的產生過程；
+* 非同步的讀寫資料庫，目前支援 PostgreSQL 和 MySQL（MariaDB）資料庫；
+* 支援非同步讀寫 Redis；
+* 基於執行緒池實作 sqlite3 資料庫的非同步讀寫，提供與上述資料庫相同的介面；
+* 支援 ARM 架構；
+* 方便的輕量級 ORM 實現，一般物件到資料庫的雙向對應；
+* 支援外掛，可透過設定檔案在載入時動態載入；
+* 支援內建插入點的 AOP；
+* 支援 C++ coroutine。
+
+## 一個非常簡單的例子
+
+不像大多數 C++ 框架，drogon 的主程式可以非常簡單。Drogon 使用了一些小技巧使主程式和控制器解耦。控制器的路由設定可以在控制器類別中定義或在設定檔案中完成。
+
+下面是一個典型主程式的樣子：
+
+```c++
+#include <drogon/drogon.h>
+using namespace drogon;
+int main()
+{
+    app().setLogPath("./")
+         .setLogLevel(trantor::Logger::kWarn)
+         .addListener("0.0.0.0", 80)
+         .setThreadNum(16)
+         .enableRunAsDaemon()
+         .run();
+}
+```
+
+如果使用設定檔案，可以進一步簡化成：
+
+```c++
+#include <drogon/drogon.h>
+using namespace drogon;
+int main()
+{
+    app().loadConfigFile("./config.json").run();
+}
+```
+
+當然，Drogon 也提供了一些函式，讓使用者可以在 `main()` 函式中直接加入控制器邏輯，例如，使用者可以註冊一個 lambda 處理常式到 drogon 框架中，如下所示：
+
+```c++
+app().registerHandler("/test?username={name}",
+                    [](const HttpRequestPtr& req,
+                       std::function<void (const HttpResponsePtr &)> &&callback,
+                       const std::string &name)
+                    {
+                        Json::Value json;
+                        json["result"]="ok";
+                        json["message"]=std::string("hello,")+name;
+                        auto resp=HttpResponse::newHttpJsonResponse(json);
+                        callback(resp);
+                    },
+                    {Get,"LoginFilter"});
+```
+
+這看起來很方便，但不適用於複雜的場景，試想如果有數十個或數百個處理函式要註冊進框架，`main()` 函式將變得難以閱讀。顯然，讓每個包含處理函式的類別在自己的定義中完成註冊是更好的選擇。所以，除非你的應用邏輯非常簡單，我們不建議使用上述介面，更好的做法是建立一個 HttpSimpleController 類別，如下：
+
+```c++
+/// The TestCtrl.h file
+#pragma once
+#include <drogon/HttpSimpleController.h>
+using namespace drogon;
+class TestCtrl:public drogon::HttpSimpleController<TestCtrl>
+{
+public:
+    void asyncHandleHttpRequest(const HttpRequestPtr& req, std::function<void (const HttpResponsePtr &)> &&callback) override;
+    PATH_LIST_BEGIN
+    PATH_ADD("/test",Get);
+    PATH_LIST_END
+};
+
+/// The TestCtrl.cc file
+#include "TestCtrl.h"
+void TestCtrl::asyncHandleHttpRequest(const HttpRequestPtr& req,
+                                      std::function<void (const HttpResponsePtr &)> &&callback)
+{
+    //write your application logic here
+    auto resp = HttpResponse::newHttpResponse();
+    resp->setBody("<p>Hello, world!</p>");
+    resp->setExpiredTime(0);
+    callback(resp);
+}
+```
+
+**上述程式的大部分程式碼都可以由 `drogon_ctl` 指令產生**（使用指令 `drogon_ctl create controller TestCtr`）。使用者只需要加入自己的業務邏輯。在這個範例中，當用戶端存取 URL `http://ip/test` 時，控制器簡單地回傳一個 `Hello, world!` 頁面。
+
+對於 JSON 格式的回應，我們可以這樣建立控制器：
+
+```c++
+/// The header file
+#pragma once
+#include <drogon/HttpSimpleController.h>
+using namespace drogon;
+class JsonCtrl : public drogon::HttpSimpleController<JsonCtrl>
+{
+  public:
+    void asyncHandleHttpRequest(const HttpRequestPtr &req, std::function<void(const HttpResponsePtr &)> &&callback) override;
+    PATH_LIST_BEGIN
+    //list path definitions here;
+    PATH_ADD("/json", Get);
+    PATH_LIST_END
+};
+
+/// The source file
+#include "JsonCtrl.h"
+void JsonCtrl::asyncHandleHttpRequest(const HttpRequestPtr &req,
+                                      std::function<void(const HttpResponsePtr &)> &&callback)
+{
+    Json::Value ret;
+    ret["message"] = "Hello, World!";
+    auto resp = HttpResponse::newHttpJsonResponse(ret);
+    callback(resp);
+}
+```
+
+讓我們更進一步，透過 HttpController 類別建立一個 RESTful API 的範例，如下所示（省略實作檔案）：
+
+```c++
+/// The header file
+#pragma once
+#include <drogon/HttpController.h>
+using namespace drogon;
+namespace api
+{
+namespace v1
+{
+class User : public drogon::HttpController<User>
+{
+  public:
+    METHOD_LIST_BEGIN
+    //use METHOD_ADD to add your custom processing function here;
+    METHOD_ADD(User::getInfo, "/{id}", Get);                  //path is /api/v1/User/{arg1}
+    METHOD_ADD(User::getDetailInfo, "/{id}/detailinfo", Get);  //path is /api/v1/User/{arg1}/detailinfo
+    METHOD_ADD(User::newUser, "/{name}", Post);                 //path is /api/v1/User/{arg1}
+    METHOD_LIST_END
+    //your declaration of processing function maybe like this:
+    void getInfo(const HttpRequestPtr &req, std::function<void(const HttpResponsePtr &)> &&callback, int userId) const;
+    void getDetailInfo(const HttpRequestPtr &req, std::function<void(const HttpResponsePtr &)> &&callback, int userId) const;
+    void newUser(const HttpRequestPtr &req, std::function<void(const HttpResponsePtr &)> &&callback, std::string &&userName);
+  public:
+    User()
+    {
+        LOG_DEBUG << "User constructor!";
+    }
+};
+} // namespace v1
+} // namespace api
+```
+
+如你所見，透過 `HttpController` 類別，使用者可以同時對應路徑和路徑參數，這對 RESTful API 應用來說非常方便。
+
+另外，你可以發現前面所有的處理函式介面都是非同步的，處理器的回應是透過回呼物件回傳的。這種設計是考慮到效能，因為在非同步模式下，可以使用少量的執行緒（例如和處理器核心數相等的執行緒）處理大量的並行請求。
+
+編譯上述所有原始檔案後，我們得到了一個非常簡單的網頁應用程式，這是一個不錯的開始。**請瀏覽 GitHub 上的[文件](https://drogonframework.github.io/drogon-docs/#/CHN/CHN-01-%E6%A6%82%E8%BF%B0)**

+FindFilesystem
+##############
+
+This module supports the C++17 standard library's filesystem utilities. Use the
+:imp-target:`std::filesystem` imported target to
+
+Options
+*******
+
+The ``COMPONENTS`` argument to this module supports the following values:
+
+.. find-component:: Experimental
+    :name: fs.Experimental
+
+    Allows the module to find the "experimental" Filesystem TS version of the
+    Filesystem library. This is the library that should be used with the
+    ``std::experimental::filesystem`` namespace.
+
+.. find-component:: Final
+    :name: fs.Final
+
+    Finds the final C++17 standard version of the filesystem library.
+
+If no components are provided, behaves as if the
+:find-component:`fs.Final` component was specified.
+
+If both :find-component:`fs.Experimental` and :find-component:`fs.Final` are
+provided, first looks for ``Final``, and falls back to ``Experimental`` in case
+of failure. If ``Final`` is found, :imp-target:`std::filesystem` and all
+:ref:`variables <fs.variables>` will refer to the ``Final`` version.
+
+
+Imported Targets
+****************
+
+.. imp-target:: std::filesystem
+
+    The ``std::filesystem`` imported target is defined when any requested
+    version of the C++ filesystem library has been found, whether it is
+    *Experimental* or *Final*.
+
+    If no version of the filesystem library is available, this target will not
+    be defined.
+
+    .. note::
+        This target has ``cxx_std_17`` as an ``INTERFACE``
+        :ref:`compile language standard feature <req-lang-standards>`. Linking
+        to this target will automatically enable C++17 if no later standard
+        version is already required on the linking target.
+
+
+.. _fs.variables:
+
+Variables
+*********
+
+.. variable:: CXX_FILESYSTEM_IS_EXPERIMENTAL
+
+    Set to ``TRUE`` when the :find-component:`fs.Experimental` version of C++
+    filesystem library was found, otherwise ``FALSE``.
+
+.. variable:: CXX_FILESYSTEM_HAVE_FS
+
+    Set to ``TRUE`` when a filesystem header was found.
+
+.. variable:: CXX_FILESYSTEM_HEADER
+
+    Set to either ``filesystem`` or ``experimental/filesystem`` depending on
+    whether :find-component:`fs.Final` or :find-component:`fs.Experimental` was
+    found.
+
+.. variable:: CXX_FILESYSTEM_NAMESPACE
+
+    Set to either ``std::filesystem`` or ``std::experimental::filesystem``
+    depending on whether :find-component:`fs.Final` or
+    :find-component:`fs.Experimental` was found.
+
+
+Examples
+********
