	47	+the other file will never be used.
	48	+
	49	+## Using the libs ##
	50	+
	51	+To pull in what you need it's enough to just write
	52	+
	53	+ find_package(ZLIB CONFIG)
	54	+
	55	+or
	56	+
	57	+ find_package(minizip CONFIG)
	58	+
	59	+in your CMakeLists.txt, however it is advised to specify what you really want via:
	60	+
	61	+ find_package(ZLIB CONFIG COMPONENTS shared static REQUIRED)
	62	+
	63	+or
	64	+
	65	+ find_package(minizip CONFIG COMPONENTS shared static REQUIRED)
	66	+
	67	+As it's possible to only build the shared or the static lib, you can make sure that everything you need
	68	+is found. If no COMPONENTS are requested, everything needs to be found to satisfy your request. If the
	69	+libraries are optional in you project, you can omit the REQUIRED and check yourself if the targets you
	70	+want to link against are created.
	71	+
	72	+When you search for minizip, it will search zlib for you, so only one of both is needed.
	73	+
	74	+## Imported targets ##
	75	+
	76	+When found the following targets are created for you:
	77	+
	78	+ ZLIB::ZLIB and ZLIB::ZLIBSTATIC -- for zlib
	79	+ MINIZIP::minizip and MINIZIP::minizipstatic -- for minizip

37	MINIZIP_BUILD_TESTING=ON -- Enable testing of minizip
38
39	MINIZIP_ENABLE_BZIP2=ON -- Build minizip withj bzip2 support
40
41	A usable installation of bzip2 is needed or config will fail. Turn this option of in this case.
42
43	MINIZIP_INSTALL=ON -- Enable installation of minizip
44
45	This option is only available on mingw as they tend to name this lib different. Maybe this will also be
46	removed in the future as. If you rely cmake for finding and using zlib, this can be turned off, as
47	the other file will never be used.
48
49	## Using the libs ##
50
51	To pull in what you need it's enough to just write
52
53	find_package(ZLIB CONFIG)
54
55	or
56
57	find_package(minizip CONFIG)
58
59	in your CMakeLists.txt, however it is advised to specify what you really want via:
60
61	find_package(ZLIB CONFIG COMPONENTS shared static REQUIRED)
62
63	or
64
65	find_package(minizip CONFIG COMPONENTS shared static REQUIRED)
66
67	As it's possible to only build the shared or the static lib, you can make sure that everything you need
68	is found. If no COMPONENTS are requested, everything needs to be found to satisfy your request. If the
69	libraries are optional in you project, you can omit the REQUIRED and check yourself if the targets you
70	want to link against are created.
71
72	When you search for minizip, it will search zlib for you, so only one of both is needed.
73
74	## Imported targets ##
75
76	When found the following targets are created for you:
77
78	ZLIB::ZLIB and ZLIB::ZLIBSTATIC -- for zlib
79	MINIZIP::minizip and MINIZIP::minizipstatic -- for minizip
