I am trying to compile libpq 17.5 on Windows 11 linking against my own build openssl 3.5.0.
When running the meson setup command it only finds openssl 3.3.0 from Strawberry perl. I tried to put my own openssl in the path but it still fails and only finds the 3.3.0 that is shipped with Strawberry Perl.
My command it this:
C:\src\pq>meson setup build -Dldap=disabled -Dnls=disabled -Dplperl=disabled -Dplpython=disabled -Dpltcl=disabled -Dllvm=disabled -Dicu=disabled -Dlz4=disabled -Dzstd=disabled -Dgssapi=disabled -Dpam=disabled -Dbsd_auth=disabled -Dsystemd=disabled -Dbonjour=disabled -Dlibxml=disabled -Dlibxslt=disabled -Dselinux=disabled -Dssl=openssl -Dextra_include_dirs="C:\src\openssl\install\include" -Dextra_lib_dirs="C:\src\openssl\install\lib" --prefix="C:\src\pq\install

As you can see it finds my openssl.exe, but there is an output: Run-time dependency openssl (modules: OpenSSL::Crypto, OpenSSL::SSL) found: YES 3.3.0. Although it still links against "C:\Strawberry\c\bin\libpq__.dll" and "C:\Strawberry\c\bin\libcrypto-3-x64__.dll".
With the old build tools in src/tools/msvc it was quite easy, I just had to put the openssl dir (C:\src\openssl\install) into the config.pl. I don't know how to do that with the Meson build and I was not able to find any information about that.
How can I define the path to use my own OpenSSL?
Set the environment variable to point to the directory that contains the .pc files for your version of OpenSSL:
set PKG_CONFIG_PATH="C:\src\openssl\install\lib\pkgconfig"
meson setup ...
That should do the trick.
