Re: Are compression requirements needed when building only libraries? - Mailing list pgsql-general

My PostgreSQL is built with support for all these libraries, and I find that my libraries are linked with "libz"

| Support for all CMake versions below 3.17.0 will be removed once
| newer CMake versions are more widely adopted. If you encounter
