Building Postgres 17.0 with meson - Mailing list pgsql-hackers

I’m trying to build Postgres 17.0 and have about learning meson as I go.

The build setup command I have so far is:
meson setup build --prefix=%prefix% --buildtype=release -Dssl=auto -Dzlib=auto -Dicu=auto

but I believe that cmd expects ssl, zlib, and icu to be installed in default locations.

How do I specify to meson that I want it to use the versions of those 3 software packages that I have built

e.g.  the openssl I want it to use is located in D:\Postgres-Builds\OpenSSL\OpenSSL-Install\OpenSSL-3.1.6-wx6

and similar locations for icu and zlib?

Thanks, Mark
