Name: zlib
Description: zlib compression library
Version: 1.2.10

Requires:
Libs: -L${libdir} -L${sharedlibdir} -lz
Cflags: -I${includedir}


pkg-config --modversion zlib
1.2.10

found this while trying to upgrade a port that now explicitly requires zlib
1.2.11 and thought I had to update to 12.2 instead of just waiting for 13, but
everything I am seeing is suggesting 1.2.11 is in the base of releng12.1 but
the pc file is versioned incorrectly. Not sure if maybe there was a reason it
was held at 1.2.10, or if it should in fact be 1.2.11

when i edit /usr/libdata/pkgconfig/zlib.pc to reflect version 1.2.11 the port
builds and runs fine, but not sure this is correct and will be clobbered on any
new patches to releng12.1 during install. releng12.2 no longer has the
lib/libz/zlib.pc file which may be the issue, perhaps it uses the
sys/contrib/zlib.pc.in file to dynamically produce the pkg-config pc file? else
the library source files seem to be identical in the git repo. 12.1 is old in
the tooth, but it is still listed as a supported version so I figured I post
the potential bug. I didn't check the 11.4 branch.
