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?
