[package] zlib-ng/2.2.5: incorrect version used in CMake config files generated by Conan

[robomics]

Description

Building the recipe with zlib_compat=True results in ZLIB_VERSION being set to zlib-ng's version, instead of zlib's version when generating e.g. FindZLIB.cmake using the CMakeDeps generator.

This is problematic, because any consumer looking for a specific version of ZLIB (e.g. like libarchive - link) will not find a compatible version, given that the major versions of zlib and zlib-ng are different.

Crucially, the *.cmake files generated by zlib-ng when installing from source use a valid zlib version (e.g. 1.3.1 in this case).

See zlib.h.in, CMakeLists.txt, and zlib-config.cmake.in.

I noticed this issue while trying to build libarchive using zlib-ng instead of zlib by adding zlib/*: zlib-ng/2.2.5 to the list of [replace_requires] in my conan profile. This results in a build failure because cmake discards the version provided by conan, and ends up looking for a static build of zlib at the system level (which is not available on my machine).

conan create --name libarchive --version 3.8.1 recipes/libarchive/all/ --build='*' -pr:a=clang  --update -o 'libarchive/*:with_zlib=True

@robomics Hello! Thank you for your very detailed issue! Indeed is not only clear your situation, but I could follow the steps easily.

I just opened the PR #28548 with a fix for your context. Please, feel free to validate it.

[robomics]

Thanks for thr quick fix @uilianries!

I can confirm that things seems to be working properly now :)
I can build libarchive with zlib-ng.

For posteriority, this is the output of the test_package generated when running the following command:

user@dev:/tmp$ conan create --name libarchive --version 3.8.1 recipes/libarchive/all/ --build=missing --build='libarchive/*' -o 'libarchive/*:with_zlib=True' -o 'zlib-ng/*:zlib_compat=True'

...

======== Testing the package: Executing test ========
libarchive/3.8.1 (test package): Running test()
libarchive/3.8.1 (test package): RUN: ./test_package
libarchive version: libarchive 3.8.1
libarchive details: libarchive 3.8.1 zlib/1.3.1.zlib-ng libb2/bundled

[uilianries]

@robomics Thank you for your feedback!

[uilianries]

@robomics Hello! The PR #28548 has been merged with the fix for this issue.

Please, feel free to update your local Conan package for zlig-ng:

conan install -r conancenter --update --requires=zlib-ng/2.2.5 --build=missing

Regards!
