Cannot configure project without mpi library

[prograholic]

I'm trying to configure boost for win32-msvc-2008 with following command:

cmake -DBUILDDIR=../build/msvc-2008 -DBUILDSTEP=configure -P build.cmake

However i does not have any mpi library, and configuration fails with error:

D:\prograholic\projects\boost\src>cmake -DBUILDDIR=../build/msvc-2008 -DBUILDSTEP=configure -P build.cmake
