When i run cmake script to configure digiKam-SC, i got this error :

CMake Error at extra/libkmap/CMakeLists.txt:41 (FIND_PACKAGE):
  Could not find module FindMarble.cmake or a configuration file for package
  Marble.

  Adjust CMAKE_MODULE_PATH to find FindMarble.cmake or set Marble_DIR to the
  directory containing a CMake configuration file for Marble.  The file will
  have one of the following names:

    MarbleConfig.cmake
    marble-config.cmake

Libkmap search MarbleConfig cmake script... I can see that marble is
not detected by this script anymore, since KDE 4.6 probably, because
under Windows with KDE 4.5.4, there is no problem...

The right script is now by this script :

bash-3.2$ pwd
/opt/local/share/apps/cmake/modules

bash-3.2$ ls *Marble*
FindMarbleWidget.cmake

Which contain this code :

bash-3.2$ cat FindMarbleWidget.cmake
# - Try to find marblewidget library
# Once done this will define
#
#  MARBLEWIDGET_FOUND - system has MARBLEWIDGET library
#  LIBMARBLEWIDGET_INCLUDE_DIR - the LIBMARBLEWIDGET include directory
#  LIBMARBLEWIDGET_LIBRARY - the marblewidget library
#
#  copyright 2008 by Patrick Spendrin <ps_ml at gmx.de>
#  use this file as you like
#

if(LIBMARBLEWIDGET_INCLUDE_DIR AND LIBMARBLEWIDGET_LIBRARY)

  # Already in cache
  set(MARBLEWIDGET_FOUND TRUE)

else(LIBMARBLEWIDGET_INCLUDE_DIR AND LIBMARBLEWIDGET_LIBRARY)
  find_path(LIBMARBLEWIDGET_INCLUDE_DIR Quaternion.h PATH_SUFFIXES marble)

  if (WIN32 AND CMAKE_BUILD_TYPE_TOLOWER MATCHES debug)
         set (LIBRARY_NAME marblewidgetd)
    else(WIN32 AND CMAKE_BUILD_TYPE_TOLOWER MATCHES debug)
        set (LIBRARY_NAME marblewidget)
  endif (WIN32 AND CMAKE_BUILD_TYPE_TOLOWER MATCHES debug)
  find_library(LIBMARBLEWIDGET_LIBRARY ${LIBRARY_NAME})

  if(LIBMARBLEWIDGET_INCLUDE_DIR AND LIBMARBLEWIDGET_LIBRARY)
    set(MARBLEWIDGET_FOUND TRUE)
  endif(LIBMARBLEWIDGET_INCLUDE_DIR AND LIBMARBLEWIDGET_LIBRARY)

  if(MARBLEWIDGET_FOUND)
    if (NOT MARBLEWIDGET_FIND_QUIETLY)
      message(STATUS "Found Marble: ${LIBMARBLEWIDGET_LIBRARY}")
    endif (NOT MARBLEWIDGET_FIND_QUIETLY)
  else(MARBLEWIDGET_FOUND)
    if(MARBLEWIDGET_FIND_REQUIRED)
      message(FATAL_ERROR "Could NOT find any Marble library")
    endif(MARBLEWIDGET_FIND_REQUIRED)
  endif(MARBLEWIDGET_FOUND)

  mark_as_advanced(LIBMARBLEWIDGET_INCLUDE_DIR LIBMARBLEWIDGET_LIBRARY)
endif(LIBMARBLEWIDGET_INCLUDE_DIR AND LIBMARBLEWIDGET_LIBRARY)

As we can see in libkmap :

https://projects.kde.org/projects/kdereview/libkmap/repository/revisions/0b63454ffd1e113340c3a52f90b706f0568eea5f

Some severals changes have been done by Michael about marble find
cmake scripts, but some transition tune need to be done to work
everywhere. I'm right ?
