0006 Findgzip
0007 --------
0008
0009 Try to find gzip.
0010
0011 If the gzip executable is not in your PATH, you can provide
0012 an alternative name or full path location with the ``gzip_EXECUTABLE``
0013 variable.
0014
0015 This will define the following variables:
0016
0017 ``gzip_FOUND``
0018     TRUE if gzip is available
0019
0020 ``gzip_EXECUTABLE``
0021     Path to gzip executable
0022
0023 If ``gzip_FOUND`` is TRUE, it will also define the following imported
0024 target:
0025
0026 ``gzip::gzip``
0027     Path to gzip executable
0028
0029 Since 5.85.0.
