Include the Necessary Files
The resource compiler error message provides a clue: "No rule to build ...". The make process requires a rule to build each type of file. There are no rules in your make file.
Look at the make files for the delivered examples. You will see that mdl.mki is %included in every one. mdl.mki, or one of the files it includes, contains the rule definitions for the build tools.
Distinguish MDL and C++ Projects
Your make file includes the following...
dirToSearch = $(MS)/mdl/include/
%include cincapnd.mki
Those are directives for the C++ compiler, but you are building a pure MDL project. Delete those lines.
