libva-dev not available for 32 bit? "ERROR: vaapi not found"

libva-dev not available for 32 bit? "ERROR: vaapi not found"

I'm trying to configure ffmpeg library for ubuntu for 32 bit.
Earlier it wasn't compiling for both 32 and 64 bit.
It was throwing this error "ERROR: vaapi not found".
Then I installed libav-dev and it configures for 64 bit.
Can't find 32 bit lib for libva-dev. Anybody knows how to approach?
