# FindQt5PlatformSupport
# -------
#
# Try to find Qt5PlatformSupport on a Unix system.
#
# This will define the following variables:
#
# ``Qt5PlatformSupport_FOUND``
#     True if (the requested version of) Qt5PlatformSupport is available
# ``Qt5PlatformSupport_VERSION``
#     The version of Qt5PlatformSupport
# ``Qt5PlatformSupport_LIBRARIES``
#     This can be passed to target_link_libraries() instead of the ``Qt5PlatformSupport::Qt5PlatformSupport``
#     target
# ``Qt5PlatformSupport_INCLUDE_DIRS``
#     This should be passed to target_include_directories() if the target is not
#     used for linking
# ``Qt5PlatformSupport_DEFINITIONS``
#     This should be passed to target_compile_options() if the target is not
#     used for linking
#
# If ``Qt5PlatformSupport_FOUND`` is TRUE, it will also define the following imported target:
#
# ``Qt5PlatformSupport::Qt5PlatformSupport``
#     The Qt5PlatformSupport 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.
