Syntax error when building on MacOS

[clemmy]

After running brew install libtool autoconf automake and running ./autogen.sh, I ran into the following error:

./configure: line 16763: syntax error near unexpected token `CAIROMM,cairomm-1.0,cairomm=yes,cairomm=no'
./configure: line 16763: `PKG_CHECK_MODULES(CAIROMM,cairomm-1.0,cairomm=yes,cairomm=no)'

I still got a build working by removing the following lines from cola/configure.ac

#AC_CHECK_LIB(cairomm-1.0,cairo_create)
PKG_CHECK_MODULES(CAIROMM,cairomm-1.0,cairomm=yes,cairomm=no)
if test "x$cairomm" = "xyes"; then
	AC_DEFINE(HAVE_CAIROMM, 1, [Enable CairoMM code])
fi

This is on macOS 11.6.1.
autoconf 2.71
automaker 1.16.5
libtool 2.4.7

For future searchers: you need to install pkg-config (brew install pkg-config) and likely rerun autoconf w/ autoconf -i -f
