# For building with cmake at least version 3.12 (minizip 3.12) is needed
|
||
|
|
|
||
|
|
In most cases the usual
|
||
|
|
|
||
|
|
cmake -S . -B build -D CMAKE_BUILD_TYPE=Release
|
||
|
|
|
||
|
|
will create everything you need, however if you want something off default you can adjust several options fit your needs.
|
||
|
|
Every option is list below (excluding the cmake-standard options), they can be set via cmake-gui or on cmdline with
|
||
|
|
|
||
|
|
-D<option>=ON/OFF
|
||
|
|
|
||
|
|
## ZLIB-options with defaults ##
|
||
|
|
|
||
|
|
ZLIB_BUILD_TESTING=ON -- Enable Zlib Examples as tests
|
||
|
|
|
||
|
|
ZLIB_BUILD_SHARED=ON -- Enable building zlib shared library
|
||
|
|
|
||
|
|
ZLIB_BUILD_STATIC=ON -- Enable building zlib static library
|
||
|
|
|
||
|
|
ZLIB_BUILD_MINIZIP=ON -- Enable building libminizip contrib library
|
||
|
|
|
||
|
|
If this option is turned on, additional options are available from minizip (see below)
|
||
|
|
|
||
|
|
ZLIB_INSTALL=ON -- Enable installation of zlib
|
||
|
|
|
||
|
|
ZLIB_PREFIX=OFF -- prefix for all types and library functions, see zconf.h.in
|
||
|
|
|
||
|
|
ZLIB_INSTALL_COMPAT_DLL=ON -- Install a copy as zlib1.dll
|
||
|
|
|
||
|
|
This option is only on windows available and may/will be turned off and removed somewhen in the future.
|
||
|
|
If you rely cmake for finding and using zlib, this can be turned off, as `zlib1.dll` will never be used.
|
||
|
|
|
||
|
|
## minizip-options with defaults ##
|
||
|
|
|
||
|
|
MINIZIP_BUILD_SHARED=ON -- Enable building minizip shared library
|
||
|
|
|
||
|
|
MINIZIP_BUILD_STATIC=ON -- Enable building minizip static library
|
||
|
|
|
||
|
|
MINIZIP_BUILD_TESTING=ON -- Enable testing of minizip
|
||
|
|
|
||
|
|
MINIZIP_ENABLE_BZIP2=ON -- Build minizip withj bzip2 support
|
||
|
|
|
||
|
|
A usable installation of bzip2 is needed or config will fail. Turn this option of in this case.
|
||
|
|
|
||
|
|
MINIZIP_INSTALL=ON -- Enable installation of minizip
|
||
|
|
|
||
|
|
MINIZIP_INSTALL_COMPAT_DLL=ON -- Install a copy as libminizip-1.dll
|
||
|
|
|
||
|
|
This option is only available on mingw as they tend to name this lib different. Maybe this will also be
|
||
|
|
removed in the future as. If you rely cmake for finding and using zlib, this can be turned off, as
|
||
|
|
the other file will never be used.
|
||
|
|
|
||
|
|
## Using the libs ##
|
||
|
|
|
||
|
|
To pull in what you need it's enough to just write
|
||
|
|
|
||
|
|
find_package(ZLIB CONFIG)
|
||
|
|
|
||
|
|
or
|
||
|
|
|
||
|
|
find_package(minizip CONFIG)
|
||
|
|
|
||
|
|
in your CMakeLists.txt, however it is advised to specify what you really want via:
|
||
|
|
|
||
|
|
find_package(ZLIB CONFIG COMPONENTS shared static REQUIRED)
|
||
|
|
|
||
|
|
or
|
||
|
|
|
||
|
|
find_package(minizip CONFIG COMPONENTS shared static REQUIRED)
|
||
|
|
|
||
|
|
As it's possible to only build the shared or the static lib, you can make sure that everything you need
|
||
|
|
is found. If no COMPONENTS are requested, everything that is found will satisfy your request. If the
|
||
|
|
libraries are optional in you project, you can omit the REQUIRED and check yourself if the targets you
|
||
|
|
want to link against are created.
|
||
|
|
|
||
|
|
When you search for minizip, it will search zlib for you, so only one of both is needed.
|
||
|
|
|
||
|
|
## Imported targets ##
|
||
|
|
|
||
|
|
When found the following targets are created for you:
|
||
|
|
|
||
|
|
ZLIB::ZLIB and ZLIB::ZLIBSTATIC -- for zlib
|
||
|
|
MINIZIP::minizip and MINIZIP::minizipstatic -- for minizip
|
