Try to find the libmount library (part of util-linux), once done this will define:
``LibMount_FOUND``
LibMount was found on the system.
``LibMount_INCLUDE_DIRS``
The libmount include directory.
``LibMount_LIBRARIES``
The libmount libraries.
``LibMount_VERSION``
The libmount version.
If ``LibMount_FOUND`` is TRUE, it will also define the following imported target:
``LibMount::LibMount``
The libmount library
Since 5.83.0
