Sometimes you want to see the actual compiler flags and definitions when compiling the code:
$ make VERBOSE=1
You can turn optimization off (debug mode) like this:
$ ./setup --type=debug [other flags]
$ cd build
$ make
You can edit compiler flags in cmake/compilers/{FortranFlags.cmake, CFlags.cmake, CXXFlags.cmake}.
Alternatively you can edit compiler flags through ccmake:
$ cd build
$ ccmake ..
