But in this case there *is* hackery :-) to set the default profile, more
specifically in cmake/Modules/OpmDefault.cmake, line 8.
Debug profile is chosen by default because most of the time you are
building from source code to develop and/or debug.
However, it is an equally valid stance that those setting up a debug
environment should do the configuration (QtCreator for instance require
the variable to be present in "cache" so it must be specified anyway),
and those just extracting a tarball should get a release build.
Technically this is an incredibly quick change; it is rather a matter of
policy. (It seems that DUNE-Autotools has -O2, but DUNE-CMake has not
(yet)). I am open to change this.
Debug symbols are always generated, regardless of the debug/release
profile (through more hackery...)
