configure: error: cannot find minizip/unzip.h, bailing out

I change system-wide library zlib to zlib-ng. System still working fine with zlib-ng, but some packages can not be recompiled with zlib-ng library.

Example of error:

checking for minizip/unzip.h... no
configure: error: cannot find minizip/unzip.h, bailing out

I try to find packages, which require minizip library. Gentoo official overlay have 19462 packages:

find /var/db/repos/gentoo -name "*\.ebuild" | awk -F":" '{print $1}' | awk -F"/" '{print $6"/"$7}' | sort -u | grep -v metadata | wc -l

There are 23 packages, which needs minizip library:

grep -r "zlib\[minizip\]" /var/db/repos/gentoo | awk -F":" '{print $1}' | awk -F"/" '{print $6"/"$7}' | sort -u | grep -v metadata | wc -l

List of packages, which require minizip library in gentoo overlay:

app-crypt/hashcat
app-office/scribus
app-text/sigil
app-text/xiphos
dev-db/spatialite
dev-games/cegui
dev-libs/quazip
dev-libs/tntnet
dev-qt/qtwebengine
games-arcade/commandergenius
games-emulation/gngeo
games-emulation/mgba
games-rpg/eternal-lands
games-rpg/grimrock
games-util/springlobby
media-libs/assimp
media-plugins/mythplugins
media-video/vlc
metadata/md5-cache
net-analyzer/wireshark
net-im/psi
net-im/vacuum
sci-geosciences/gpsbabel
sci-visualization/scidavis

Some packages, which require minizip library in my system can be found in Gentoo bug-tracking system

In some cases, where package support built-in zlib version, like hashcat and perl, I just configure packages to use built-in zlib library. Wireshark can be compiled without zip compression support, which based on minizip library, so I use Wireshark without zip support. But in case of ungoogled-chromium package, which use only external zlib library, I can not add original zlib library in simple way.

I report bug to https://github.com/Eloston/ungoogled-chromium/issues/1598. And I want to find a way to integrate zlib-ng and minizip-ng libraries into packages that require a minizip/unzip.h file.

How to integrate zlib-ng and minizip-ng libraries into packages that require a minizip/unzip.h file?

minizip-ng library installed too.

File /usr/lib64/libminizip.so.1 and /usr/lib64/libminizip.so.1.0.0 - are part of removed zlib library, and remained in system only as dependency of ungoogled-chromium package.

Running cmake with -DMZ_COMPAT=ON will produce unzip.h and zip.h.

[joebonrichie]

Set INSTALL_INC_DIR=/usr/include/minizip. Applications generally expect the headers to be in /usr/include/minizip/.h instead of /usr/include/.h. Maybe this should be set as part of MZ_COMPAT.
