本文主要是介绍【Qt】ubuntu QtCreator的pro文件中使用pkg-config，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
试验环境
ubuntu14.04.5
opencv2.4.13.6
Qt Creator 4.0.3
Qt 5.6
使用方法
在pro文件中，添加opencv头文件路径
INCLUDEPATH += /usr/local/opencv2.4.13.6/include
添加pkg-config –libs opencv
CONFIG += link_pkgconfig
PKGCONFIG += opencv
可以在命令行下，先测试pkg-config –libs opencv，有的opencv名字为opencv2.4
$ pkg-config –libs opencv
-L/usr/local/opencv2.4.13.6/lib -lopencv_calib3d -lopencv_contrib -lopencv_core -lopencv_features2d -lopencv_flann -lopencv_gpu -lopencv_highgui -lopencv_imgproc -lopencv_legacy -lopencv_ml -lopencv_nonfree -lopencv_objdetect -lopencv_ocl -lopencv_photo -lopencv_stitching -lopencv_superres -lopencv_ts -lopencv_video -lopencv_videostab -lrt -lpthread -lm -ldl
