The page:

http://svn.boost.org/trac/boost/wiki/CMakeBuildConfiguration

says the following under the bolded CMakeCache.txt title:

<--- cut here ---
The same information is stored in a file CMakeCache.txt located in the
build directory. For this reason, after you've done the initial
configuration of a build directory you can invoke ccmake like this:

ccmake <path-to-build>

or have the makefiles do it for you:

make edit_cache

The CMakeLists.txt file is hand-editable, though this is usually not
as convenient as the cmake-supplied configuration tools mentioned
above. An excerpt of this file:

//
// Enable/Disable color output during build.
//
CMAKE_COLOR_MAKEFILE:BOOL=ON

//
// Use versioned library names, e.g., boost_filesystem-gcc41-1_34
//
BUILD_VERSIONED:BOOL=ON

 >--- cut here ---

The CMakeCache.txt title indicates the filename is
CMakeCache.txt(which is only in the build directory); yet, the text
mentions CMakesLists.txt (which is only in the source
directory). Since the string ':BOOL' only occurs in the
CMakeCache.txt, I assume the phrase:

   CMakeLists.txt file is hand-editable

on the above page should be:

   CMakeCache.txt file is hand-editable

However, even in CMakeCache.txt there was no BUILD_VERSIONED:BOOL.
OTOH, apparently the flag is ON because when I ran make,
the library names in the build directory included:

   libboost_date_time-gcc41-1_35_1.so.1.35.1
                      ^^^^^

and I did specify g++-4.1.

So, is the BUILD_VERSIONED flag no longer valid or is there
some other way to set it?
