Could you build out-of-source in a small path?
like

small/path/build
when your source would be in
long/path/source

cpack should only work with file in the build tree.

this is a workaround but it may work.

By the way:
  Which version of CMake/CPack are you using?
  With which platforms/compiler combination(s) are your working?
