gnome-icon-theme dependency

[Lev Babiev <harley hosers org>]

Hello all,

Looking through configure, gnome-icon-theme dependency is mandated for 
with_platform=gnome only because there is no clean way to check for 
presence of hicolor-icon-theme. Unfortunately, there is no option to 
select a generic *nix platform (gnome,win32 and hildon are the only 
acceptable options). Would it make sense to add another platform choice?

Looking through configure.ac, adding another acceptable choice in 
AC_ARG_WITH("platform" ...) would be the only change necessary. This 
option can be called "linux" or "generic". Without any changes to 
configure it would configure evince without any usual gnome deps and 
warn about requirement for hicolor-icon-theme.

Cheers,
Lev
