问题
在使用confluent-kafka-go 时遇到如下问题：
$ go build t.go
# pkg-config --cflags rdkafka
Package rdkafka was not found in the pkg-config search path.
Perhaps you should add the directory containing `rdkafka.pc'
to the PKG_CONFIG_PATH environment variable
No package 'rdkafka' found
pkg-config: exit status 1
解决办法：
文件~/.bashrc 末尾添加
export PKG_CONFIG_PATH=/usr/lib/pkgconfig
使之生效：
$ source ~/.bashrc
