You have these choices:

     1. Use a pattern rule
     2. Use a static pattern rule
     3. Set .SECONDEXPANSION and use $$* (requires newer versions of
        make)

You can find discussions of these in the GNU make manual.  Personally I
would use a pattern rule; this is what they were designed for:

        %.exe: %.o
                $(LINK.cc) $^ -o $@
        EmployeeTest.exe: Employee.o
        DatabaseTest.exe: Employee.o Database.o
