Qt+CMake应用开发

Qt+CMake应用开发

• 开发环境：
  • Qt5.15.2 + Qt Creator 12.01 + CMake3.28.0-rc3 + MSVC2015
  • Qt5.15对CMake的支持非常友好，只需要安装CMake并添加环境就行，基本不需要做过多的配置

环境配置

• Qt5.15对CMake的支持非常友好，只需要安装CMake并添加环境就行，基本不需要做过多的配置

QtCreator新建项目

• 新建项目和Qt创建项目时一样，只是在”Define Build System“选择CMake作为构建系统，而不是qmake。
• 构建器笔者使用的是MSVC2015，可自行根据需求选择
• 创建完成后QtCreator 会自动生成 CMakeLists.txt
