Yes, and LDFLAGS should then be used in test_t rule.

But, both by convention and by implicit rules implementation, the C++ 
compiler is contained in CXX variable (and not CC, which is supposed to 
be C compiler) with its compile flags being stored in CXXFLAGS variable. 
By properly setting CPPFLAGS (preprocessor flags (-I, -D, ...) for both 
CC and CXX) , CXXFLAGS, and LDFLAGS you can build test_t purely by using 
implicit rules.
