My mistake...


http://www.cmake.org/cmake/help/cmake2.6docs.html#command:set

   set(<variable> <value> [[CACHE <type> <docstring> [FORCE]] | 
PARENT_SCOPE])

Should be:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} /EHa" CACHE STRING "cxx flags" 
FORCE)

This will still be odd for your users.  It will also append /EHa every 
time CMake is run...
