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 and SunOS, 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.
#]=======================================================================]

# On the BSD's, inotify is implemented through a library, libinotify.
if(CMAKE_SYSTEM_NAME MATCHES "Linux" OR CMAKE_SYSTEM_NAME MATCHES "SunOS")
