[Insight-users] Re: Configuring ITK + VTK + FLTK project with CMake

[Luis Ibanez]

Hi Yuanjie,


CMake has support for facilitating the
configuration of a project that uses FLTK.

However, FLTK itself is not build with
CMake. Please follow the build instructions
provided by FLTK in order to build this
GUI Toolkit.

   http://www . fltk . org/faq . php


In order to use ITK, VTK and FLTK in your
project, the CMakeLists.txt file of your
project just need to contain the following
lines

----------------------------------

PROJECT( myApplicationName )

#
#  FIND ITK
#
FIND_PACKAGE(ITK)
IF (USE_ITK_FILE)
  INCLUDE (${USE_ITK_FILE})
ELSE (USE_ITK_FILE)
  MESSAGE( FATAL_ERROR "This application requires ITK. One of these
components is missing. Please verify configuration")
ENDIF (USE_ITK_FILE)


#
# FIND VTK
#
FIND_PACKAGE(VTK)
IF (USE_VTK_FILE)
  INCLUDE (${USE_VTK_FILE})
ELSE (USE_VTK_FILE)
  MESSAGE( FATAL_ERROR "This application requires VTK. One of these
components is missing. Please verify configuration")
ENDIF (USE_VTK_FILE)



#
# FIND FLTK
#
FIND_PACKAGE(FLTK)
IF (FLTK_FOUND)
  INCLUDE_DIRECTORIES (${FLTK_INCLUDE_DIR})
ELSE (FLTK_FOUND)
  MESSAGE( FATAL_ERROR "This application requires FLTK. One of these
components is missing. Please verify configuration")
ENDIF (FLTK_FOUND)


INCLUDE_DIRECTORIES(
  ${myApplicationName_SOURCE_DIR}
  )

#
#  Define the list of source files
#
SET(APPLICATION_SOURCES
  SourceFile1.cxx
  SourceFile2.cxx
  SourceFile3.cxx
  vtkFlRenderWindowInteractor.cxx
  )


ADD_EXECUTABLE( myApplication ${APPLICATION_SOURCES})

FLTK_WRAP_UI(myApplication myApplicationGUI.fl)

-----------------------------------

Note the use of the command:

FLTK_WRAP_IU( )  for managing the fluid files *.fl




Regards,



   Luis
