Actually better:
set (foo_DEFS _TYPE1_)
set (bar_DEFS _TYPE2_)
foreach(i foo bar)
add_executable(${i} main.c)
set_target_properties(foo PROPERTIES COMPILE_DEFINITIONS ${${i}_DEFS})
foreach(flag RELEASE DEBUG)
set_target_properties(foo PROPERTIES COMPILE_DEFINITIONS_{flag}
${${i}_DEFS})
endforeach(flag)
endforeach(i)
