[Bug] configure error happens when run ./configure cmd #15

Cloudberry Database version

the latest main branch.

What happened

When I run the ./configure cmd at the CBDB directory, the configure error happens.

configure: error: The pkg-config script could not be found or is too old.  Make sure it
is in your PATH or set the PKG_CONFIG environment variable to the full
path to pkg-config.

Alternatively, you may set the environment variables ZSTD_CFLAGS
and ZSTD_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

To get pkg-config, see <http://pkg-config.freedesktop.org/>.
See `config.log' for more details

But I run the same cmd, it works for PostgreSQL project.

What you think should happen instead

When running the cmd ./configure, it should run successfully without errors.

How to reproduce

1. Clong the CBDB repo
2. Change to CBDB dir, and run the cmd ./configure

Operating System

macOS 13.2.1(Apple M1)

Anything else

This is my config.log file, PTAL.
