[Unix] 如果pkg-config找不到某库的路径

pkg-config的原理是:每个由pkg-config管理的库都会提供一个后缀为.pc的文件,pkg-config不过是把这个文件读出,分析并打印在屏幕上罢了。

比如opencv的pc文件(opencv.pc):

# Package Information for pkg-config

prefix
=/usr/local
exec_prefix
=${prefix}
libdir
=${exec_prefix}/lib
includedir_old
=${prefix}/include/opencv
includedir_new
=${prefix}/include

Name: OpenCV
Description: Open Source Computer Vision Library
Version:
2.2.0
Libs: -L
${libdir} -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d -lopencv_objdetect -lopencv_contrib -lopencv_legacy -lopencv_flann
Cflags: -I
${includedir_old} -I${includedir_new}

如果pkg-config找不到某个库的路径,需要做的就是找到该库的pc文件,然后拷到pkg-config指定的路径下就行了。pc文件一般在编译时会生成,pkg-config指定的路径,在osx下如果是用macports安装的pkg-config,则会在/opt/local/lib/pkgconfig。
