Subject: Documentation: Specify Doxygen OUTPUT_DIRECTORY explicitly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, doxygen is run by ninja in the top-level build directory,
therefore the "Documentation" folder is always created there. However,
when libcamera is built as a subproject, it should not touch the
top-level build directory because it can cause conflicts and because
the documentation won't be created where meson thinks it will be, so
the "doxygen" target will always be dirty and installation will fail.
