hi John

try this CmakeLists.txt it works with most of the wx samples.

####################### CmakeLists.txt
PROJECT( MYPROJECTNAME )

SET( wxWidgets_USE_LIBS  base core adv gl html xml xrc expat jpeg png
	regex tiff zlib)

#----- Setup wxWidgets
FIND_PACKAGE(wxWidgets)
IF (wxWidgets_FOUND)
    #wxWidgets includes files
    INCLUDE( ${wxWidgets_USE_FILE} )
ELSE (wxWidgets_FOUND)
    MESSAGE(FATAL_ERROR
        "Cannot build without WxWidgets.  Please set WXWIDGETS_DIR.")
ENDIF (wxWidgets_FOUND)

#----- Setup OS files
IF( WIN32)
    # This is for window
    SET(OS_FILES WIN32)
    # on win is it *.rc
    SET(PROJECT_RC_FILE sample.xpm)
ELSE( WIN32)
    # Not window
    SET(PROJECT_RC_FILE sample.xpm)
ENDIF( WIN32)

#-----  this find and setup the vtk
FIND_PACKAGE(VTK)
IF (VTK_FOUND)
  INCLUDE(${VTK_USE_FILE})
ELSE(VTK_FOUND)
  MESSAGE(FATAL_ERROR
     "Cannot build without VTK.  Please set VTK_DIR.")
ENDIF (VTK_FOUND)

#----- Setup the source files
SET(SOURCE_FILES isosurf.cpp isosurf.h)

#----- make the exe projects

#----- link the libraries with the exe projects
