Findgzip
--------

Try to find gzip.

If the gzip executable is not in your PATH, you can provide
an alternative name or full path location with the ``gzip_EXECUTABLE``
variable.

This will define the following variables:

``gzip_FOUND``
    TRUE if gzip is available

``gzip_EXECUTABLE``
    Path to gzip executable

If ``gzip_FOUND`` is TRUE, it will also define the following imported
target:

``gzip::gzip``
    Path to gzip executable

Since 5.85.0.
