[Boost-cmake] Problem building NSIS installer.

Subject: [Boost-cmake] Problem building NSIS installer.

Hello,

I've been trying to build the NSIS installer, so that I can install
only the headers for the libraries that I need. Please bear in mind
that I don't have much experience with either CPack or NSIS, but I'm
still trying to debug the issue...

I'm getting the error output below when I run "CPack -G NSIS"

----------------------------------------

Error in script
"C:/cygdir/builds/boost/_CPack_Packages/win32/NSIS/project.nsi" on
line 32365 -- aborting creation process
----------------------------------------

If I edit the project.nsi to include the following declarations:

...
Var python_headers_selected
Var python_headers_was_installed
...

and run the command manually ("C:/.../NSIS/makensis.exe"
"C:/.../_CPack_Packages/win32/NSIS/project.nsi") it creates the
Boost-1.40.0-vc8.exe file. Although it produces several warning
messages posted at the end of this message.

Now, I still have problems because when I run the installer it can't
"download" the packages... I suppose that this is because the cpack
process is not complete (note that if I run cpack again it overwrites
the changes to the project.nsi and bails out with error again).

So, I guess my question is how do I go about solving this? What
variable in the boost cmake files creates the dependency on the
python_headers_* variables in the CPack/NSIS process?

Any help debugging this will be greatly appreciated.
