./configure error ....even though file exsit...

I'd like to comple vlc-0.8.6c with Cygwin compiler for windows vlc.

I downlaod contrib-20070530-win32-bin-gcc-3.4.5-only.tar.bz2 and extract it
to /usr/win32

I alway met errors .... while runing ./configure

checking for NOTIFY... no
checking for liveMedia/libliveMedia.a in /usr/win32/live.com...
/usr/win32/live.
com/liveMedia/libliveMedia.a
checking dvdread/dvd_reader.h usability... no
checking dvdread/dvd_reader.h presence... no
checking for dvdread/dvd_reader.h... no
configure: error: cannot find libdvdread headers




I can see all dvd related files... in /usr/win32/include/dvd*
I don't know why ./configure can able to find... DVD related files...
