How to solve "undefined reference to 'wiringPiSetup'" [message #1837295]

I created my own SIFB in 4diac and write code in it，when I rebuild my forte ， the compilation failed and said "undefined reference to 'wiringPiSetup". My procedure is as follows. wiringPi. h and pcf8591.h are located in /usr/include.

Did I make a mistake in cmakelists. txt？
How should I write？
Or is it something else？
How to solve?
