title: Building AOSP, vendor_module_check.mk fail
body: <p>I'm trying to include the Google Mobile Services apps in my AOSP build for Nexus 10 (manta).  I created a <code>vendor</code> folder in my root directory and modified the full_manta.mk file by adding these lines:</p>
  
  <pre><code># Include GMS apps
  $(call inherit-product, $(SRC_TARGET_DIR)/product/generic.mk)
  $(call inherit-product, vendor/google/products/gms.mk)
  </code></pre>
  
  <p>Next, I do <code>. build/envsetup.sh</code> and then <code>lunch</code> (I select 13 for full_manta-user-debug build).  Then I type <code>make -j32</code> to build and get the following error:</p>
  
  <pre><code>build/core/tasks/vendor_module_check.mk:60: *** Error: vendor module "Books" in  vendor/google/apps with unknown owner "" in product "full_manta".  Stop.
  </code></pre>
  
  <p>I'm not sure what the issue is.  I'm also a make file noob so I can't really understand what's in the <code>vendor_module_check.mk</code> file other than the fact that the error is being generated around here:</p>
  
  <pre><code>$(foreach m, $(_vendor_check_modules), \
    $(if $(filter vendor/%, $(ALL_MODULES.$(m).PATH)),\
      $(if $(filter $(_vendor_owner_whitelist), $(ALL_MODULES.$(m).OWNER)),,\
        $(error Error: vendor module "$(m)" in $(ALL_MODULES.$(m).PATH) with unknown owner \
          "$(ALL_MODULES.$(m).OWNER)" in product "$(TARGET_PRODUCT)"))\
      $(if $(ALL_MODULES.$(m).INSTALLED),\
        $(eval _vendor_module_owner_info += $(patsubst $(PRODUCT_OUT)/%,%,$(ALL_MODULES.$(m).INSTALLED)):$(ALL_MODULES.$(m).OWNER)))))
  
  endif
  </code></pre>
  
  <p>Anyone have any similar experiences or know what the error is?</p>
