#  macro for common setup of plugins, examples and applications it expect some variables to be set:
#  either within the local CMakeLists or higher in hierarchy
#  TARGET_NAME is the name of the folder and of the actually .exe or .so or .dll
#  TARGET_TARGETNAME  is the name of the target , this get buit out of a prefix, if present and TARGET_TARGETNAME
#  TARGET_SRC  are the sources of the target
#  TARGET_H are the eventual headers of the target
#  TARGET_LIBRARIES are the libraries to link to that are internal to the project and have d suffix for debug
#  TARGET_EXTERNAL_LIBRARIES are external libraries and are not differentiated with d suffix
#  TARGET_LABEL is the label IDE should show up for targets

# This set up the libraries to link to, it assumes there are two variable: one common for a group of examples or plagins
# kept in the variable TARGET_COMMON_LIBRARIES and an example or plugin specific kept in TARGET_ADDED_LIBRARIES 
# they are combined in a single list checked for unicity 
# the suffix ${CMAKE_DEBUG_POSTFIX} is used for differentiating optimized and debug
#
# a second variable TARGET_EXTERNAL_LIBRARIES hold the list of  libraries not differentiated between debug and optimized
