Subject: [PATCH] package.bbclass: Fix broken dev package dependency.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, the process_pkgconfig() would process only the
"Requires" key field and ignore "Requires.private" while
generating the dev dependency chain.

Example: usr/lib/pkgconfig/libical.pc
----------
Libs: -L${libdir} -lical -licalss -licalvcal
Libs.private: -lpthread
Requires.private: icu-i18n
----------
Depends field generated for libical-dev
Depends: glib-2.0-dev, libical (= 3.0.7-r0)
------------

When trying to resolve the build time dependency with libical
package using “-dev” ipk generated, it will throw the below error.
-----------
Package icu-i18n was not found in the pkg-config search path.
Perhaps you should add the directory containing `icu-i18n.pc'
to the PKG_CONFIG_PATH environment variable
Package 'icu-i18n', required by 'libical', not found
-----------

This patch will add the packages listed in "Requires.private"
to the dependency chain.

-------
