glibtoolize: error: One of these is required: glibtoolize: gm4 gnum4 m4 glibtoolize: error: Please install GNU M4, or 'export M4=/path/to/gnu/m4'.

Hi, I'm trying to install btcdeb. I'm using MacOS 13.1

I did the following steps:

1. Cloning the source code using "git clone https://github.com/bitcoin-core/btcdeb"
2. Then I went on the btcdeb directory and I run the first command "./autogen.sh"

It keeps saying "glibtoolize: error: One of these is required: glibtoolize: gm4 gnum4 m4 glibtoolize: error: Please install GNU M4, or 'export M4=/path/to/gnu/m4'."

The problem is that I already installed m4 using brew install m4.

Thanks
