Somehow I fail to find the difference between 2.4.6 and 2.4.7 RC11.

If you remove the EXCLUDE_FROM_ALL from the ADD_LIBRARY() command, make and 
make install work in both cases (but the EXCLUDE_FROM_ALL target will still 
be built on make install, which shouldn't happen, but it doesn't seem to 
break anything here).

If I use only EXCLUDE_FROM_ALL, then make; make install fails both with 2.4.6 
and 2.4.7RC11.

How can I reproduce the problem ?

As a workaround, you could use something like this:

option(BUILD_SOMETHING "build something FALSE)
if (BUILD_SOMETHING)
  add_executable(hello2 main2.c)
  install(TARGETS hello2 DESTINATION bin)
endif (BUILD_SOMETHING)
