CMake can't find minizip but I can use zlib

Question

I'm trying to use minizip in the zlib library. I'm compiling on CentOS and got zlib using

yum -y install zlib-devel

The problem is, when compiling (and linking to the libz.so library file), it looks like I can get everything in zlib, but none of the header files or function for minizip can be found. For example, find_package(ZLIB REQUIRED) works, and so does #include <zlib.h>, but #include <minizip/zip.h> returns file not found.

Following the instructions from John's blog on minizip https://nachtimwald.com/2019/09/08/making-minizip-easier-to-use/

pkg_check_modules(MZIP minizip REQUIRED) is giving me minizip not found.

Looking at rpm -ql zlib-devel gives

/usr/include/zlib.h
/usr/lib64/libz.so

I thought everything in minizip would just be part of libz.so? Or do I need to do something more to link to minizip? Thanks.

No, minizip is not part of the zlib library. It is included in the zlib source code distribution, along with several other third-party contributions, in the contrib/ directory.

You would need to compile it yourself.

Thanks for the response! Are the yum install minizip-devel packages still outdated, or are they also up to date now? – ruisen2000 Jul 03 '21 at 07:03

I have no idea. I don't even know what "yum" is, except something I say after eating ice cream. – Mark Adler Jul 03 '21 at 17:46
