variables - 使用 qmake 变量

Question

有没有办法让 qmake 替换这样的自定义变量？换句话说，我希望将 $(LIBS) 替换为变量 LIBS，以便我可以轻松地更改机器之间的包含路径。提前谢谢了!

LIBS = c:/tmp/libs.pfo
INCLUDEPATH += . \
$(LIBS)/OpenCV2.1-msvc/include \
$(LIBS)/OpenCV2.1-msvc/modules/core/include \
$(LIBS)/OpenCV2.1-msvc/modules/imgproc/include \
...

我也试过这个无济于事:

LIBS = c:/tmp/libs.pfo
INCLUDEPATH += . \
$$quote($$LIBS/OpenCV2.1-msvc/include) \
$$quote($$LIBS/OpenCV2.1-msvc/modules/core/include) \
$$quote($$LIBS/OpenCV2.1-msvc/modules/imgproc/include) \
...

更新:在看到另一个线程后，我尝试了第三个技巧，它奏效了! qmake can't evaluate a proper variable

LIBS = c:/tmp/libs.pfo
INCLUDEPATH += . \
$$quote($${LIBS}/OpenCV2.1-msvc/include) \
$$quote($${LIBS}/OpenCV2.1-msvc/modules/core/include) \
$$quote($${LIBS}/OpenCV2.1-msvc/modules/imgproc/include) \
