Macos issue (Meson)

If libreadline is not found in pkg-config, at first check if it's already installed with this command:

pkg-config --libs readline

If it returns something like -L/opt/homebrew/Cellar/readline/8.3.3/lib -lreadline then you can add libreadline to your PKG_CONFIG_PATH:

export PKG_CONFIG_PATH=$(brew --prefix readline)/8.3.3/lib/pkgconfig:$PKG_CONFIG_PATH"

otherwise, you can install it with Homebrew:

brew install readline
