Actually everything works for me. I do not need this anymore since clang is now the system standard compiler
on my OS, so I can mostly use dunecontrol as in the autotools days with no problems (using the dune tarballs).

For the OPM modules I work on, I do not use dunecontrol. I use the cmake -C option to save time/bugs when configuring.

It could be that cmake behaviour has changed when it comes to switching compilers, because at least earlier I had problems
with it, yet you report that setting the flag on the command line works now. I am not a cmake expert!
