Hi Chao,

The $x is getting parsed by the makefile so you need to escape it with the
$ makefile escape sequence. Try:
add_custom_command(TARGET temp_target
POST_BUILD
COMMAND for x in a b c\;
do echo $$x \;
done\;)
You can see the difference in a make VERBOSE=1 :
[100%] Linking C static library libtemp_target.a

-P CMakeFiles/temp_target.dir/cmake_clean_target.cmake

Now becomes:
