I finally did this:

set ( samples
     sample1
     ...
     samplen
     )

foreach ( proj ${samples} )
     add_executable ( ${proj} ${proj}/${proj}.cpp )
     target_link_libraries( ${proj} ${Boost_LIBRARIES} )
endforeach ()

This works fine.

The macro approach would work too, I guess, thanks.
