cmake/build.mk

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

Following a discussion we had earlier about improving cmake support,
I've created a devel/cmake/build.mk (to match devel/meson/build.mk).

Compare to 'USE_CMAKE' it adds support for multiple BUILD_DIRS, has
better defaults, and adds support for building using ninja-build.

I've tried it out on archivers/libzip, diff attached.

I think this can go in now and can then be improved in-tree; if a
package doesn't work well with it, it can keep using USE_CMAKE for
now, but the long-term plan is to migrate from USE_CMAKE to including
this new file and removing the USE_CMAKE support from the
infrastructure.

Comments?
 Thomas
