I think the relevant details are that:

- There is a strict separation of build products from what gets
checked out of source control; that is, the build and source
directories for packageN will be different.  libpackageN.so and
packageN/somepython.py will exist in completely different places
before installation, and these places will be different when "built"
and after installation.

-  "/path/to/stacks/stackN/packageN" won't exist, per se.  But
/path/to/share/packageN/anything_you_like may exist (if packageN
chooses to install things that way).  The point is that /path/to will
be the CMAKE_INSTALL_PREFIX, and under this prefix things will be
installed in as FHS-ish a scheme as possible.

My instinct says that we should discuss what the contents of
/path/to/share/projectN/ will contain.  The only directory that is
spoken for already is cmake/.

So, something like...


I don't have a good sense of what the specifics should be.
