Having trouble compiling with Clang 18 due to outdated zlib

[djmittens]

Hi, i just upgraded my llvm on mac M1, (im using the latest version of bullet in a cmake project, 3.25).

And im getting a zlib error,

im seeing a similar issue in this issue from cmake itself https://gitlab.kitware.com/cmake/cmake/-/issues/25755 and the solution seems to be to upgrade the version of zlib.
