Can't build UIC samples

Hi all!

I downloaded IPP samples from Intel web page for IPP 7.1. I also installed CMake 2.8.10.2 and Active Perl 5.16. I tried to build samples in accordance  with guide from Intel. I also set path to *.h and *.lib of IPP in PATH variable. But when I tried to start build (perl build.pl --cmake=uic,ia32,vc2010,d,mt,release), I got an error message : "Intel(R) IPP was not found".

May be build procedure requires some additional settings?
