# 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 varibale 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
