override_dh_auto_configure not called

[Mathieu Malaterre <mathieu.malaterre@gmail.com>]

Dear all,

  I am trying to only build doc as indep target. I have the following
rules file (copy/paste from dh(1)):

...
%:
	dh --parallel --with quilt --buildsystem=cmake $@

override_dh_auto_configure:
	dh_auto_configure -- -DCMAKE_BUILD_TYPE:STRING=Release
-DCMAKE_SKIP_RPATH:BOOL=ON

build: build-arch build-indep ;
build-indep:
	$(MAKE) doc

build-arch:
	$(MAKE) all
...

However it looks like the configure step is being skipped

...
No patches applied
   dh_clean -O--parallel -O--buildsystem=cmake
 dpkg-source -b flann-1.6.8
dpkg-source: info: using source format `3.0 (quilt)'

How can I have the configure step being called and have a build-indep target

Thanks
