It worked

This behaviour is different from bjam. If ZLIB_INCLUDE_DIR is not defined and ZLIB_SOURCE is defined, bjam builds a zlib library automatically with boost prefix. Same is the case for bzip2 as well. CMake is not considering Source directories for the same. Is this the intended behaviour ?

Not that this is an issue for me, but just out of curiosity.

One more thing I've observed is the Install target. The boost include headers are installed in ${CMAKE_INSTALL_PREFIX}/include, instead of ${CMAKE_INSTALL_DIRECTORY}/include/boost-1_41. I'm using cmake for my project and cmake checks for include/boost-1_41/boost/version.hpp file (I'm using cmake-2.8)

Due to this my cmake script is not finding out boost. So this behaviour is also changed ?

Thanks,
