Subject: [PATCH] Our FLTK patches modified FLTK's autotools-based build system
 so that HAVE_XFIXES and HAVE_XCURSOR were defined in FLTK's config.h, but
 those changes never made it into the CMake-based build system used by the
 in-tree version of FLTK.  Further, our build system was allowing silent
 failures whenever Xft, Xinerama, Xcursor, or Xfixes were not present on the
 build system.  Now, the lack of these libraries is treated as a fatal error,
 since these libraries are critical for TigerVNC functionality.
