### Notice: 
###    This Makefile assumes CASA+CASACore enviroment. 
###    For who wants to build ASAP with older CASA without CASACore, 
###    1. Replace $(CASAPATH) with $(AIPSPATH). 
###    2. CASAINC should be 
###        '-I$(CASAROOT)/code/include -I$(CASAROOT)/code/casa'
###    3. Replase library names in G2CARCH '-lcasa_*' with '-l*'.
###    4. Comment-IN the definition of 'CXXOPTS'.
