Oh. I actually saw that on CI at some point... That one is definitely
odd. Currently CI for OSX builds like

    - brew install make coreutils ccache icu4c lz4 tcl-tk openldap
    - brew install meson ninja python@3.9
..
        PKG_CONFIG_PATH="/usr/local/opt/openssl/lib/pkgconfig:$PKG_CONFIG_PATH"
        PKG_CONFIG_PATH="/usr/local/opt/icu4c/lib/pkgconfig:$PKG_CONFIG_PATH"
        PKG_CONFIG_PATH="/usr/local/opt/openldap/lib/pkgconfig:$PKG_CONFIG_PATH"

        export PKG_CONFIG_PATH

        meson setup --buildtype debug -Dcassert=true -Dssl=openssl build

but I set that up knowing little about macos.


For the autoconf build CI currently does something similar via
        LIBS="/usr/local/lib:$LIBS"
        INCLUDES="/usr/local/include:$INCLUDES"
...
        LIBS="/usr/local/opt/openldap/lib:$LIBS"
        INCLUDES="/usr/local/opt/openldap/include:$INCLUDES"
        ...
          --with-includes="$INCLUDES" \
          --with-libs="$LIBS" \

are you doing something like that? Or does it work for you without? I vaguely
recall hitting a similar problem as you report when not passing
/usr/local/... to configure.

you can change it for an existing builddir with
meson configure -dldap=disabled or when setting up a new builddir by passing
-dldap=disabled at that time.

They're homebrew python deps: https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/python@3.9.rb#L28
which are optional things enabled explicitly:
