Vladimír Vondruš 7abb12c826 FindDevIL: Make the ILUT library optional
Some distributions (such as ArchLinux) have only the IL and ILU
libraries and since these are mainly used, the module should succeed
even though ILUT was not found.  Removed it from the FPHSA() macro call,
making it effectively optional.

# This module locates the developer's image library.
# http://openil.sourceforge.net/
#
# This module sets:
#
# ::
#
# IL_LIBRARIES - the name of the IL library. These include the full path to
# the core DevIL library. This one has to be linked into the
# application.
# ILU_LIBRARIES - the name of the ILU library. Again, the full path. This
# library is for filters and effects, not actual loading. It
# doesn't have to be linked if the functionality it provides
# is not used.
# ILUT_LIBRARIES - the name of the ILUT library. Full path. This part of the
# library interfaces with OpenGL. It is not strictly needed
# in applications.
# IL_INCLUDE_DIR - where to find the il.h, ilu.h and ilut.h files.
# IL_FOUND - this is set to TRUE if all the above variables were set.
# This will be set to false if ILU or ILUT are not found,
# even if they are not needed. In most systems, if one
# library is found all the others are as well. That's the
# way the DevIL developers release it.
# TODO: Add version support.
# Tested under Linux and Windows (MSVC)
