I searched the whole machine but that file is not there. It seems like it didn't get installed.

 Short, but perhaps inadequate, answer -
Add --enable-osmesa to your Mesa configure switches.

 I've no real understanding of what paraview is, but I found that
second link very confusing and apparently contradictory.  Some of it
looks out of date for current versions of Mesa (particularly,
--with-driver=xlib : I guess that --with-egl-platforms="x11" *might*
be the switch to use in 9.0 and later, but I've no idea if you need
other things there (on a a desktop I specify drm,x11), or if you
need any other--enable switches, or if you need to specify any
gallium drivers.

 From memory, Mesa-7 used to try to build everything, so specifying
the driver was a way of cutting it down.  With Mesa-{8,9} my
impression is that you may need to add extra switches to enable some
things (and the switches might differ for different versions).

 Maybe paraview users can give you more guidance on configuring
recent versions of Mesa.
