added dpcg_for_dg.cpp/hpp into CMakeLists.txt in the src/solvers/ path and then it compiles using cmake on dutinwn locally -- error in naming dpcg_for_dg.cpp in the same CMakeLists.txt-- fixed now
 removed openMP from calculation of nnz_w1 and nnz_w2 in the makeZlSSD function in src/solvers/deflation/dpcg.cpp. it seemed to give memory errors in valgrind and caused CPU only version of duncans' code to fail
