# 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.
