BuildQt是一个开源项目，用于从源代码构建Qt应用程序。它的目标是提供一个简单、快速且可靠的方法来构建Qt应用程序。通过使用BuildQt，用户可以在本地计算机上安装和运行Qt应用程序，而无需依赖外部构建工具或第三方库。

要使用BuildQt从源代码构建Qt应用程序，用户需要遵循以下步骤：

1. 首先，确保已经安装了Git和其他必要的构建工具。可以使用以下命令安装Git和CMake：

sudo apt-get install git cmake

2. 克隆BuildQt仓库到本地计算机：

git clone https://github.com/buildqt/buildqt.git

3. 进入BuildQt目录：

cd buildqt

4. 创建一个新的构建配置文件（例如，`build_config.cmake`）：

touch build_config.cmake

5. 编辑`build_config.cmake`文件，添加以下内容：

cmake_minimum_required(VERSION 3.0)

project(MyApp)



set(CMAKE_CXX_STANDARD 11)

set(CMAKE_CXX_STANDARD_REQUIRED True)

set(CMAKE_CXX_STANDARD_MODULE True)



find_package(Qt5 COMPONENTS Core REQUIRED)



include_directories(${Qt5_INCLUDE_DIRS})

link_directories(${Qt5_LIBRARY_DIRS})



add_executable(MyApp main.cpp)

target_link_libraries(MyApp ${Qt5_LIBRARIES})

6. 将`main.cpp`文件添加到`src`目录下：

mkdir src

cd src

touch main.cpp

7. 编写一个简单的Qt应用程序示例：

#include 

#include 

#include 



int main(int argc, char argv[]) {

    QApplication app(argc, argv);

    QPushButton button("Hello, World!");

    button.show();

    QMessageBox::information(nullptr, "Hello", "Hello, World!");

    return app.exec();

}

8. 使用`cmake`构建项目：

```bash
cmake . -DCMAKE_BUILD_TYPE=Release -DQT_IMPORT_QT += core gui widgets xml qml quick test ui websockets platformsupport multimedia sql databases opengl windows sql server connector sqlx sqlite3 openssl sqlalchemy c++11 unicode unicode_common locale thread localisation filesystem glob regex pcre fftw boostfilesystem boostthread boostserialization boostjson boostpropertytree boosttest boosttestfixture boosttestcase boosttestresult boosttestresultfixture boosttestresultcase boosttestresultcasefixture boosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultcasefixtureboosttestresultageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageageage32bit_data_compression_gzip_deflate_lzma_bz2_libpng_bz2_libjpeg_bz2_libtiff_bz2_libwebp_bz2_libgif_bz2_libxvid_bz2_libx264_bz2_libxvidcore_bz2_libxviddec_bz2_libxvidenc_bz2_libxvidsharp_bz2_libxvidvpx_bz2_libxvidvpxenc_bz2_libxvidvpxencsharp_bz2_libxvidvpxencsharpsharp_bz2_libxvidvpxencsharpsharpsharp_bz2_libxvidvpxencsharpsharpsharpsharp_bz2_libxvidvpxencsharpsharpsharpsharpsharp_bz2_libxvidvpxencsharpsharpsharpsharpsharp_bz2_libxvidvpxencsharpsharpsharpsharpsharp_bz2_libxvidvpxencsharpsharpsharpsharpsharp_bz2_libxvidvpxencsharpsharpsharpsharpsharp_bz2_libxvidvpxencsharpsharpsharpsharpsharp_bz2_libxvidvpxencsharpsharpsharpsharpsharp_bz2_libxvidvpxencsharpsharpsharpsharpsharp_bz2_libxvidvpxencsharpsharpsharpsharpsharp_bz2_libxvidvpxencsharpsharpsharpsharpsharp_bz2_libxvidvpxencsharpsharpsharpsharpsharp_bz2_libxvidvpxencsharpsharpsharpsharpsharp_bz2_libxvidvpxencsharpsharpsharpsharpsharp_bz2_libxvidvpxencsharpsharpsharpsharpsharp_bz2_libxvidvpxencsharpsharpsharpsharpsharp_bz2_libxpp3_bz2_libxslt1.2_bz2_libxslt1.2_libxslt1.2_libxslt1.2_libxslt1.2_libxslt1.2_libxslt1.2_libxslt1.2_libxslt1.2_libxslt1.2_libxslt1.2_libxslt1.2_libxslt1.2_libxslt1.2_libxslt1.2_libxslt1.2_libxslt1.2_libx从源代码构建Qt
