Hi

I use Ubuntu 12.04 and I want to compile the file using crypt.h and unistd.h but to start function crypt() I should use additional options -lm -lcrypt as in terminal:
arm-linux-gnueabi-g++ -g3 -pg -Wall *.cpp *.h -o access.cgi -lm -lcrypt
I don't know where should I add declaration. On internet I find that I should add it to Cmake file but I dont know how?
