#  macro for linking libraries that come from Findxxxx commands, so there is a variable that contains the
#  full path of the library name. in order to differentiate release and debug, this macro get the
#  NAME of the variables, so the macro gets as arguments the target name and the following list of parameters
#  is intended as a list of variable names each one containing  the path of the libraries to link to
#  The existance of a variable name with _DEBUG appended is tested and, in case it' s value is used
#  for linking to when in debug mode
#  the content of this library for linking when in debugging
