Adding parameters to conditional '--with' in the command line

[dletai]

In configure it's often required to do something along the lines of ./configure --with-feature=path for example
--with-nvml=/usr/local/cuda

Using %bcond_with mechanism, there doesn't seem to be a way to make this happen in command line, aside from something like
rpmbuild -rb --define '_with_nvml --with-nvml=/usr/local/cuda'
instead of the more intuitive (but not working)
rpmbuild -rb --with nvml=/ur/local/cuda

Is there a way (maybe with %bcond) to pass such arguments from intuitive command line to %configure (possibly with some handling by %if %(with xxx) construct?

Indeed, there's currently no built-in way for the --with foo=<arg> syntax on the CLI.

Another workaround that comes to mind (that's perhaps a bit cleaner/clearer than defining the _with_foo macro directly):

rpmbuild -rb --with nvml --define 'nvml_path /usr/local/cuda'

The in the spec file:

%configure \
   %{?with_nvml:--with-nvml=%{nvml_path}}

Although that's still not ideal, of course.
