I checked out CMake-2-4 from CVS which calles itself as
"cmake version 2.4-patch 7 RC-11"

The pkg-config manpage lists several directories in PKG_CONFIG_PATH, 
conditionally overriden by PKG_CONFIG_LIBDIR. If the latter is set, 
installing to one in PKG_CONFIG_LIBDIR might be more feasable.
Or is "share/pkgconfig" always the right choice?

Ok.
Even that would be a valid documentation (saves people the time to search for 
one).
