dpkg-buildpackage and new "-indep" debhelper options

[Anton Gladky]

Thank you, Roger, for your extended response.

I am trying it to do it now, using new -indep and -arch options.

> Are you using the latest debhelper?
Yes, 8.9.11

I have simplified debian/rules:

====================================
#! /usr/bin/make -f
BUILDDIR = $(CURDIR)/debian/build

%:
	dh $@ --buildsystem=cmake --builddirectory=$(BUILDDIR)

override_dh_auto_build-indep:
	cd $(BUILDDIR); $(MAKE) doc
====================================

But I still have a problem. Docs are building with "-B" option.

"dpkg-buildpackage -B" calls "dh build", but it should call "dh
build-arch", isn't it?

Thanks.
Anton
