#! Macro camitk_extension simplifies writing a camitk extension (component, action)
#!
#! The name of the extension is automatically the name of the directory from where this macro
#! is called, unless it is overriden by the TARGET_NAME parameter.
#!
#!  usage:
#! \code
#!    extension(<type>
#!                     [DISABLED]
#!                     [NEEDS_QT_MODULES]

#!                     [TARGET_NAME non-default-targetname]
#!     )
#! \endcode
#!
#! \param <type>                    = The selected type of extension you wish to build.
#                                     possible values : ACTION_EXTENSION or COMPONENT_EXTENSION.
#! \param DISABLED                  = means this is a not a default extension, it will not be compiled automatically
#! \param NEEDS_QT_MODULES          = add this if your library depends on Qt modules, such as QtCore, QtGui, QtMultimedia, QtNetwork, QtOpenGL, QtScript, QtScriptTools, QtSql, QtSvg, QtWebkit, QtXml, QtXmlPatterns, QtDeclarative
#! \param NEEDS_ITK                 = add this if your component needs itk.
#!                                    Do not forget to add the needed list of itk libraries in the LIBRARIES parameter
#! \param NEEDS_LIBXML2             = add this if your component needs libxml2
#! \param NEEDS_XSD                 = add this if your action needs Codesynthesis xsd cxx (xml schema compiler)
#! \param NEEDS_OPENCV              = add this if your component needs OpenCV
#! \param NEEDS_IGSTK               = add this if your component needs IgsTK
#! \param NEEDS_XERCESC             = add this if your action / component needs XercesC library
#! \param NEEDS_CEP_LIBRARIES       = list of needed CEP libraries (not external dependencies)
#! \param NEEDS_COMPONENT_EXTENSION = list of needed component extensions
#! \param NEEDS_ACTION_EXTENSION    = list of needed component extensions
#! \param INCLUDE_DIRECTORIES       = additional include directories
#! \param DEFINES                   = list of define flags to add at compilation time
#! \param EXTERNAL_SOURCES          = list of extra source/headers files (external to the current directory)
#!                                    that needed to be added to the SOURCES variable.
#!                                    Note: EXTERNAL_SOURCES are not installed
#! \param EXTERNAL_LIBRARIES        = external libraries to add to the link command
#! \param HEADERS_TO_INSTALL        = list of headers to install, if present this will automatically
#!                                    create an "install-COMPONENT_NAMEcomponent" target, that can be used
#!                                    anywhere else to manage dependencies to this component.
#!                                    The headers are installed ${CAMITK_BUILD_INCLUDE_DIR}/COMPONENT_NAME
#!                                    when the target "install-COMPONENT_NAMEcomponent" is called.
#! \param INSTALL_ALL_HEADERS       = install all of the headers (this is the lazy solution, please consider
#!                                    making a list and using HEADERS_TO_INSTALL parameter instead!
#! \param TARGET_NAME               = specify a target name different than the default (default is the action/component directory name)
#!                                    this can be very useful for example when you have action/component directory in your CEP that has
#!                                    the same name as one in the camitk opensource.
#! \param CEP_NAME                  = specify the CEP_NAME, which is used to categorized the extension for packaging purpose
#!                                    No CEP_NAME provided will result in default categorization (generic extension).
#! \param DESCRIPTION               = Simple description of the extension. Used for packaging presentation for instance.
#! \param NEEDS_GDCM                = Add this, if your extension requires GDCM 2.x library
