对包含目录使用多个 -I 标志，对 lib 目录使用多个 -L 标志

On Linux you need to use -Ibefore each directory that you want to add.
在 Linux 上，您需要-I在要添加的每个目录之前使用。
Example:
例子：
user:/home/my_project$ gcc -g -Wall -I/usr/include/lib_Directory/ -I./include -c ./src/transcod.c
./means the current directory where you are running the command, in this case my_project;
./表示您运行命令的当前目录，在本例中为my_project；
