使用 pkg-config 输出将库链接到 QT 项目
这是一个新手问题.我正在尝试将 OpenCV 库添加到 QT 项目中.
This is a bit of a newbie question. I am trying to add the OpenCV libraries to a QT project.
这个问题表示链接标志由
pkg-config --libs opencv
如果我将命令行输出粘贴到项目文件中，例如:
If I paste the command line output into the project file like:
LIBS += -L/usr/local/lib -lml -lcvaux -lhighgui -lcv -lcxcore
然后一切都可以正常编译，但现在这不是可移植的.如何简单地引用命令的输出?
then everything compiles fine, but now this isn't portable. How can I simply reference the output of the command?
更新:尝试了 Ken Bloom 的建议，但无法编译.实际生成的编译器命令是
Update: Tried Ken Bloom's suggestion, but it won't compile. The actual generated compiler commands are
# How it should be, at least on my machine
g++ -o QOpenCVTest main.o qopencvtest.o moc_qopencvtest.o -L/usr/lib -L/usr/local/lib -lml -lcvaux -lhighgui -lcv -lcxcore -lQtGui -lQtCore -lpthread
# with CONFIG and PKGCONFIG
g++ -o QOpenCVTest main.o qopencvtest.o moc_qopencvtest.o -L/usr/lib -lQtGui -lQtCore -lpthread
推荐答案
CONFIG += link_pkgconfig
PKGCONFIG += opencv
