Fixed, thanks.

This is the intended way for dashboard scripts.

Great!

I doubt it would make much difference. Most of the configuration
time is spent waiting for try_compile to complete and such, though
I've never timed it.
You could do this to apply flags to bootstrap and configuration
steps but not to the tests:
```
set(ENV{CXXFLAGS} "-O3 -DNDEBUG")
set(ENV{CFLAGS} "-O3 -DNDEBUG")
set(CTEST_BUILD_CONFIGURATION "")
macro(dashboard_hook_build)
unset(ENV{CXXFLAGS})
unset(ENV{CFLAGS})
endmacro()
```

That would be nice if anyone has time. However, I think at least some
of them may be testing per-config behavior, so by adding `-DNDEBUG`
to the all-config flags they get confused.
