-odefaultly means-o2forifort/ifxand-o0forgfortran, I think it's better to use exact-o0,-o1, or-o2in theCMakeLists.txt, to keep consistent among different compilers. Then, I tried to reorganize theCMakeLists.txtto accept the argumentOPT_LEVELto specify the optimization level for non-Debug configs, like O0, O1, O2, O3. Actually, I did account for an inconsistent behavior between/O2and/O1when working withMSVC 2015+ifort 17.0. The/O2got wrong, and theO1and Debug mode got the correct and same results.
