pkg-config使用

pkg-config用来得到已安装library的信息，这些信息从扩展名为.pc的文件中获得。事实上，pkg-config从prefix/lib/pkgconfig目录中查找这些.pc文件，同样也可以向PKG_CONFIG_PATH环境变量中指定。下面是一个.pc文件的例子：

prefix=/home/hp/unst   # this defines a variable
exec_prefix=${prefix}  # defining another variable in terms of the first
libdir=${exec_prefix}/lib
includedir=${prefix}/include
