cmake工程导入编译好的qwt 6.2.0外部库

新建CMake + Qt项目

# 在生成你的应用add_executable之前添加qwt外部库，你可以在你的工程中创建3rdparty文件夹，然后将上述网盘下载的qwt放置其中
include_directories(${CMAKE_CURRENT_SOURCE_DIR}/3rdparty/qwt/src)
set(qwt_lib_dir ${CMAKE_CURRENT_SOURCE_DIR}/3rdparty/qwt/lib)
set(qwt_lib ${qwt_lib_dir}/qwt.lib)
set(qwt_designer_lib ${qwt_lib_dir}/qwt_designer_plugin.lib)
# 在你的应用程序生成的地方之后，添加链接qwt外部库
target_link_libraries(loadqwt PRIVATE Qt${QT_VERSION_MAJOR}::Widgets ${qwt_lib} ${qwt_designer_lib})

可以结合我之前编译qwt的博客文章来查看，将你新建的工程ui文件用designer打开，然后拖动qwt控件上去
在这里插入图片描述
点击Qt Creator的运行按钮，此处一定要选择release运行，因为的库是release的链接库，当然我是debug版本也是放了的，这就要你在cmakeLists.txt里把release和debug的不同运行方式的库放对应好。

qwt的编译及打包使用就都完成了，接下来就是查阅qwt文档，将项目的二维绘图使用qwt来完成项目功能的开发了
