FindDeflate
--------
Find the native Deflate includes and library.
IMPORTED Targets
^^^^^^^^^^^^^^^^
This module defines :prop_tgt:`IMPORTED` target ``Deflate::Deflate``, if
Deflate has been found.
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables:
::
Deflate_INCLUDE_DIRS - where to find deflate.h, etc.
Deflate_LIBRARIES - List of libraries when using deflate.
Deflate_FOUND - True if deflate found.
::
Deflate_VERSION_STRING - The version of deflate found (x.y.z)
Deflate_VERSION_MAJOR - The major version of deflate
Deflate_VERSION_MINOR - The minor version of deflate
Debug and Release variants are found separately.
