Testing of the release candidate for emacs-26.2 on Oracle Solaris 11.4
shows that a build fails because lcms2.h is not found in /usr/include.
On that system, and on Hipster, an OpenSolaris relative, that file is
present in /usr/include/lcms.

Discussions with Eli Zaretskii <eliz <at> gnu.org> suggest that emacs'
configure.ac needs to use pkg-config to identify the correct include
directory for lcms2.h:

	% pkg-config --cflags lcms2
	-I/usr/include/lcms

This change already exists in master (Bug#30346). The commit is:

    cb3863370cbe574810f796726faa39ba0de0a429

I tried cherry picking it into emacs-26 and while it needed some
manual cleanup, which was simple, Emacs still builds here after
applying it.

Thanks for pointing this out.

Thanks.  It's too late for Emacs 26.2, I think, but we could
cherry-pick it after the release, in case there will be 26.3.
