Would it be sufficient to change the cmake flags OSMESA_INCLUDE_DIR and
OSMESA_LIBRARY in CMakeCache file to point to the external build of Mesa
11.x.x?

Simply swapping the libraries won't work. Mesa 11.2 [1] added new API
OSMesaCreateContextAttribs() which is needed to create correct OpenGL
context.  The API is used at compile time if appropriate osmesa.h is
being used.

You can try to update Projects/unix/osmesa.cmake in the superbuild
source to use the configure arguments you used, and also change
versions.cmake in the same repo to point to change the osmesa source
tar ball to be 11.2. Now the superbuid will build 11.2 instead and it
should then have the new API available.
