CMake has no formal knowledge of such decorations.  This may change in
the future but for now it is up to user code to deal with them.

Are you talking about finding the installed boost library with a
FIND_LIBRARY?  You should be able to identify most of the information
you need to compute the name of the desired library in CMake code.  For
example:

IF(CMAKE_COMPILER_IS_GNUCXX)
  SET(TOOLSET "-gcc")
ENDIF(CMAKE_COMPILER_IS_GNUCXX)
IF(MSVC7)
  SET(TOOLSET "-vc7")
ENDIF(MSVC7)
