QT的项目工程默认使用的是qmake,这本来也没什么问题。但是由于要用到vcpkg这个工具来管理第三方库,好像这个 vcpkg工具只能在cmake的项目中才能使用。
于是这里记录下QT的cmake工程配置,需要注意的是需要额外配置个项:
-DCMAKE_PREFIX_PATH=D:\Qt\Qt5.10.0\5.10.0\msvc2015\lib\cmake
-DCMAKE_TOOLCHAIN_FILE=F:\vcpkg\scripts\buildsystems\vcpkg.cmake -Wno-dev
另外需要注意的是,在QT的环境中可以直接运行能出来界面没问题。
在其他环境下,得先记得先打包导出才行! 之前就是忘了这个差点以为代码配置问题。
Qml的打包和QT传统的打包方式也是不同的。
QT的打包可以用这个:
D:\Qt\Qt5.10.0\5.10.0\msvc2015\bin\windeployqt.exe -no-angle -no-opengl-sw test.exe
QML的应用打包,通过cd命令到你的exe存放的地方,并输入下面的命令:
windeployqt -qmldir "源码路径" test.exe --release
命令执行完后,在你exe生成的目录里生成qt的依赖文件。 如果你的源码使用了三方库或者生成了动态链接库,那么需要手动将需要的dll文件复制到目录下,实际运行试试,是不是可以正常运行。
CmakeLists.txt 配置模板如下:
这里面每一项的含义,好像都能看懂。总之比makefile好看多了,再也不愿回到makefile了。
需要多总结多记,看的多用的多了就熟了吧。
预定义变量
PROJECT_NAME
项目名称
PROJECT_SOURCE_DIR
工程的根目录
PROJECT_BINARY_DIR
执行cmake命令的目录
PROJECT_BINARY_DIR
执行cmake命令的目录
CMAKE_CURRENT_SOURCE_DIR
当前CMakeLists.txt文件所在目录
CMAKE_C_FLAGS
设置C编译选项
CMAKE_CXX_FLAGS
设置C++编译选项
CMAKE_C_COMPILER
设置C编译器
CMAKE_CXX_COMPILER
设置C++编译器
EXECUTABLE_OUTPUT_PATH
设置编译后可执行文件目录
LIBRARY_OUTPUT_PATH
设置生成的库文件目录
常用规则
cmake_minimum_required(VERSION 3.16) 指令cmake 版本project(hello_world) 设置工程名include_directories({PROJECT_SOURCE_DIR}/include) 添加头文件路径link_directories({PROJECT_SOURCE_DIR}/lib) 添加链接库的路径add_subdirectory(module)添加 module 子目录, 此目录下也要有CMakeLists.txt文件add_executable(project1 main.c)指定编译的可执行文件add_library(lib1 SHARED library.c library.h)指定生成的库文件,SHARED是生成动态库,STATIC后生成静态库 add_compile_options() 添加编译选项target_link_libraries()指定动态链接库install()指定make install的目录
