I have not tried yet, but I guess that the directory in which our 
install script installs the Quiche pkg-config module file 
(/usr/lib/pkgconfig) is not in the default pkg-config path on openSUSE. 
This is also the case on RH-based distributions where we had to add [1] 
/usr/lib/pkgconfig to PKG_CONFIG_PATH for Quiche to be detected.

Can you try setting 
PKG_CONFIG_PATH=/usr/lib/pkgconfig:/usr/lib64/pkgconfig at the end of 
your configure line?
