Makefile to setup regression

[sythe]

I am writing a makefile to do a regression suite.
It is using the 3 step approach in Cadence (compile (ncvhdl) , elaborate (ncelab), simulate(ncsim))

The makefile includes a testcases.mk which looks like :

testcase_list = \
  testcase1 \
  testcase2 \

I want to use this list in my Makefile to pass on each testcase item as variable to ncelab with the -gpg option.

....
...
compile:
  ncvhdl blahblah

regression_test: compile
  for testcase in $(testcase_list); \
  do \
    echo $$testcase
    ncelab $(NCELAB_OPTS) -gpg 'TESTCASE => "$testcase"' \ ;
  done

I am horribly failing to use the variable testcase to call with ncelab.

any one a suggestion ?
