[CMake] FLTK issue with cmake

[André EBERSOLD]

I'm facing some problems with FLTK too.

On linux, when you build and install FLTK with cmake, there is a file FLTKConfig.cmake installed in directory <FLTK INSTALL PREFIX>/CMake

When you invoke cmake -D FLTK_DIR=<FLTK_INSTALL PREFIX>/CMake  .  every thing is found properly. (at least for me).

What I don't understand is why in the FindFLTK.cmake file
is there a line that SETS FLTK_INCLUDE_DIR to FLTK_DIR?  
when using the FLTKConfig.cmake file, the proper directory should be ${FLTK_DIR}/../include  that's were the include files are installed. (for FLTK 1.3)



FindFLTK.cmake part
...

IF(FLTK_BUILT_WITH_CMAKE)
    SET(FLTK_FOUND 1)
    INCLUDE(${FLTK_DIR}/FLTKConfig.cmake)

    # Fluid
    IF(FLUID_COMMAND)
      SET(FLTK_FLUID_EXECUTABLE ${FLUID_COMMAND} CACHE FILEPATH "Fluid executable")
    ELSE(FLUID_COMMAND) 
      FIND_PROGRAM(FLTK_FLUID_EXECUTABLE fluid PATHS 
        ${FLTK_EXECUTABLE_DIRS}
        ${FLTK_EXECUTABLE_DIRS}/RelWithDebInfo
        ${FLTK_EXECUTABLE_DIRS}/Debug
        ${FLTK_EXECUTABLE_DIRS}/Release
        NO_SYSTEM_PATH)
    ENDIF(FLUID_COMMAND)
    # MARK_AS_ADVANCED(FLTK_FLUID_EXECUTABLE)

    SET(FLTK_INCLUDE_DIR ${FLTK_DIR})
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^I think this is not correct.
    LINK_DIRECTORIES(${FLTK_LIBRARY_DIRS})

May be someone else can share his thoughts about this subject.

Kind  regards,
Andre E.
