I haven't tried building the installer in a while and, at the moment,
I don't even have access to a Windows machine. But I'll see if I can
help!

I have a very silly question: is there a variable "Python_headers"
somewhere in project.nsi? Python seems to be the only library that has
a capitalized module name, so I'm wondering if that's the issue...

The URL for downloading packages can be set in the configuration. When
the full CPack process completes, the CPackUploads directory will
contain a bunch of files that will need to be made available at that
URL. Alternatively, you can set the "monolithic" option to build all
of the packages into the installer itself.

It starts with the cpack_add_* macros that get expanded from various
macros in Boost's tools/build/CMake/BoostCore.cmake. These macros set
many CPACK_* variables in CPackConfig.cmake, which are used by the
CPack process to create project.nsi. If the tiny patch at the end of
this doesn't help, then we'll need to trace through the CPack process
to see why the python_headers_* variables aren't getting created.
Oh, one question: did you build the "modularize" target and then
re-run CMake before building the NSIS package? That step is needed to
get all of the headers in the right places. Note that it pretty much
destroys your Subversion checkout, though, so perhaps do it on a copy
of your Subversion working copy.
