[CMake] current cmake cvs doesn't compile

[Andy Cedilnik]

Hi Alex,

 From man:

NAME
       setenv - change or add an environment variable

SYNOPSIS
       #include <stdlib.h>

       int setenv(const char *name, const char *value, int overwrite);

       int unsetenv(const char *name);


That said, I will fix it.

       Andy
