According to the documentation CMAKE_INSTALL_MANDIR should be the
standard variable, similar to --mandir with automake.  We set this
when using cmake to ${PKGMANDIR} to get most things to install
correctly.

Some packages use their own variable for this though, in which case we
just have to work around them, and perhaps educate upstream about
trying to stick to the official variable.
