I think this bug report is about adding new programs to the test suite.  
I don't think Sandeep is asking how to add more test programs to the 
test suite; he is asking how to add new Makefiles to the test suite to 
make it run new experiments that it did not run previously.

As context, several previous research projects used an interface within 
the old autoconf test suite to extend it to compile programs with 
different compiler options and run performance experiments on them.  For 
example, the SAFECode and Automatic Pool Allocation projects added rules 
to compile and run programs with additional transforms and to record the 
results in CSV files which could be imported into other programs for 
creating graphs for papers.  All of this could be done without modifying 
any files within the test-suite project; one simply created additional 
Makefiles, set come variables on the make command line, and fired off 
the experiments with "make."

I believe Sandeep is asking whether similar functionality exists within 
the new Cmake build system and, if so, how to use it.  I am curious, 
too.  It would make running some experiments for my research projects 
more convenient.  I just assumed this feature was deprecated as I got 
the impression that I was the only one still using it.
