# FindInotify
# --------------
#
# Try to find inotify on this system. This finds:
# - libinotify on Unix like systems, or
# - the kernel's inotify on Linux systems.
#
# This will define the following variables:
#
# ``Inotify_FOUND``
# True if inotify is available
# ``Inotify_LIBRARIES``
# This has to be passed to target_link_libraries()
# ``Inotify_INCLUDE_DIRS``
# This has to be passed to target_include_directories()
#
# On Linux, the libraries and include directories are empty,
# even though ``Inotify_FOUND`` may be set to TRUE. This is because
# no special includes or libraries are needed. On other systems
# these may be needed to use inotify.
#
# Since 5.32.0.
