+Subject: [PATCH] Add drm-lease client support to eglfs kms backend
+
+This patch is adding drm-lease-manager client support to Qt eglfs backend.
+When this patch is enable, Qt wayland compositor and Qt eglfs without
+compositor possible to use leased drm device.
+
+List of environment variable:
+
+QT_QPA_EGLFS_DRMLEASE :
+ When this variable is set, drm-lease-manager client support is enable.
+ Shall set drm lease device such as `card0-LVDS-1`, `card0-HDMI-A-1 ` and etc.
+
+DLM_RUNTIME_PATH :
+ It use drm-lease-manager client, typically it need to set own.

++# FindLibdlmclient
++# -------
++# FindLibdlmclient.cmake is created based on FindLibinput.cmake
++#
++# Try to find libdlmclient on a Unix system.
++#
++# This will define the following variables:
++#
++# ``Libdlmclient_FOUND``
++# True if (the requested version of) libdlmclient is available
++# ``Libdlmclient_VERSION``
++# The version of libdlmclient
++# ``Libdlmclient_LIBRARIES``
++# This can be passed to target_link_libraries() instead of the ``Libdlmclient::Libdlmclient``
++# target
++# ``Libdlmclient_INCLUDE_DIRS``
++# This should be passed to target_include_directories() if the target is not
++# used for linking
++# ``Libdlmclient_DEFINITIONS``
++# This should be passed to target_compile_options() if the target is not
++# used for linking
++#
++# If ``Libdlmclient_FOUND`` is TRUE, it will also define the following imported target:
++#
++# ``Libdlmclient::Libdlmclient``
++# The libdlmclient library
++#
++# In general we recommend using the imported target, as it is easier to use.
++# Bear in mind, however, that if the target is in the link interface of an
++# exported library, it must be made available by the package config file.
