Then I attempted to "generate" and this is where the first problem appeared. During generation on Windows (through the MSVC Command prompt/32 bit) CMake is now looking for $BOOST_ROOT/build/CMakeLists.txt file which it did NOT do on OS X. I am using the same set of options on each platform.

There are memory leak bugs that are not getting fixed, bjam just sucks to use, and the shear size of boost is just insane for my project (and others needing my project). So a small subset of Boost is really all that is required. I can embed this into my project and the size of my project will not get too out of hand. .

I think that is great. Any idea if the boost powers that be will allow you to commit that? If not, perhaps it could be distributed with the CMake boost?
