Thanks All.
Finally have written the following codes:
my $HOME = $ENV{HOME};
my $shell = shift || (getpwuid($<))[8];
my $command = "${HOME}/.project_setup";
my @setup = `$shell -c \". $command ; env\"`;
foreach (@setup) {
      if (/^(\S+)=(.*)$/) {
            my ($key, $value) = ($1, $2);
            #print ("$key => $value\n");
            $ENV{$key} = $value;
      }
}
print "$ENV{INCLUDE}\n";
