QT6.9中opencv引用路径的其中一种设置

RC_ICONS=appimage.ico

unix|win32: LIBS += -L$$PWD/opencv455/vc15/lib/ -lopencv_world455

INCLUDEPATH += $$PWD/opencv455/include

DEPENDPATH += $$PWD/opencv455/include

RC_ICONS 为指定图标文件，只写图标名appimage.ico，那么一般和pro文件在同一目录

$$PWD的意思为.pro文件所在的目录

如pro文件中：INCLUDEPATH += $$PWD/opencv455/include

$$quote关键字为在pro文件中加入带空格的路径

如：

1. LIBS += -L$$quote(C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib)
2. INCLUDEPATH += $$quote(C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Include)
