Title:
  cmake module for FLTK broken

Status in fltk1.3 package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu Xenial (a.k.a. development release)
  cmake 3.3.2is3.2.2-0ubuntu2
  I expect the FLTK module in cmake to:
  a) not require fluid when I specifically set(FLTK_SKIP_FLUID True)
  This is not the case. I get an error saying cmake cannot find fluid.  So I add it to the BuildDepends (control file).
  It still cannot find it (why is it looking anyway??) 
  so I
  IF(NOT EXISTS ${FLTK_FLUID_EXECUTABLE})
      # Try to detect full path anyway
      EXECUTE_PROCESS(COMMAND which fluid OUTPUT_VARIABLE FLTK_FLUID_EXECUTABLE OUTPUT_STRIP_TRAILING_WHITESPACE)
      IF(NOT EXISTS ${FLTK_FLUID_EXECUTABLE})
          MESSAGE(FATAL_ERROR "Please install the fluid binary which is part of FLTK.")
      ENDIF()
  ENDIF()

  Great... now it cannot find "${FLTK_INCLUDE_DIR}"
  I hack that.
  Now I get this:
  Could NOT find FLTK (missing: FLTK_INCLUDE_DIR)
  Call Stack (most recent call first):
    /usr/share/cmake-3.2/Modules/FindPackageHandleStandardArgs.cmake:374 (_FPHSA_FAILURE_MESSAGE)
    /usr/share/cmake-3.2/Modules/FindFLTK.cmake:318 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
    CMakeLists.txt:11 (FIND_PACKAGE)

  Does this module work for anything at all?
  This s rather frustrating :(

  I have tried using
  FIND_PACKAGE(FLTK REQUIRED)
  and
  FIND_PACKAGE(FLTK REQUIRED NO_MODULE)  ## this worked in 12.04 and 14.04 just fine.. found everything with some hacking

  Please fix this....

  The issue seems to be that
  /usr/lib/fltk/FLTKConfig.cmake
  does not look like this
  #
  # FLTKConfig.cmake - FLTK CMake configuration file for external projects.
  #
  # This file is configured by FLTK and used by the UseFLTK.cmake module
  # to load FLTK's settings for an external project.

  set(FLTK_FOUND TRUE)
  set(FLTK_VERSION 1.3.0)

  set(FLTK_FLUID_EXECUTABLE "/usr/bin/fluid")

  set(FLTK_USE_FILE "/usr/lib/fltk/UseFLTK.cmake")

  set(FLTK_DIR "/usr/lib/fltk")

  set(FLTK_BIN_DIR "/usr/bin")
  set(FLTK_LIB_DIR "/usr/lib/x86_64-linux-gnu")
  set(FLTK_INCLUDE_DIR "/usr/include")
  set(FLTK_DATA_DIR "/usr/share/fltk")
  set(FLTK_DOC_DIR "/usr/share/doc/fltk1.3-doc")

  set(FLTK_SHARED_LIBS_FOUND ON)
  set(FLTK_CAIRO_FOUND TRUE)
  set(FLTK_GL_FOUND TRUE)
  set(FLTK_THREADS_FOUND TRUE)
  set(FLTK_PTHREADS_FOUND TRUE)
  set(FLTK_BUILTIN_JPEG_FOUND FALSE)
  set(FLTK_BUILTIN_ZLIB_FOUND FALSE)
  set(FLTK_BUILTIN_PNG_FOUND FALSE)
  set(FLTK_XINERAMA_FOUND TRUE)
  set(FLTK_XFT_FOUND TRUE)
  set(FLTK_XDBE_FOUND TRUE)

  include("/usr/lib/fltk/FLTKLibraries.cmake")
