Trying to build miniunzip utility from contrib/minizip after an
autoreconf -f produces
[...]
In file included from minizip.c:61:0:
zip.h:50:18: fatal error: zlib.h: No such file or directory
unless zlib is already installed. Use AM_CFLAGS to set the include
path and library path to point to the just-build copy of zlib to
fix this. (This was already done for libminizip but not the binaries
that use it before this patch.)
