Carton doesn't pass PERL_CPANM_OPT?

[jwittkoski]

If I have:

export PERL_CPANM_OPT='--configure-args=CCFLAGS="-I/some/path/include"'

when I do carton install and carton calls cpanm to install a module cpanm doesn't seem to see this setting.

If I install directly with cpanm it does.

Carton overrides PERL_CPANM_OPT. There's currently no way to pass per-dist configuration flags in Carton.

So PR #199 would address this, correct? Although it would apply to every call to cpanm, not per-dist.

Ok, did some testing, #199 alone doesn't help because:

        $cmd = $self->append_args($cmd, 'configure') if $depth == 0;

And depth always seems to be > 0 even if the module is listed in cpanfile (that is, not a sub-dependency) so the configure-args are never appended.
