I would run a cmake script with ${CMAKE_COMMAND} -P.
The script can use set(ENV{VAR}) and execute_process().
This has the advantage of being more portable than bash or batch scripts.

You can pass parameters to the script with -D (have to be listed before -P).

One of those parameters can be a generator expression that will expand 
to the location of the actual target to be executed. e.g. 
$<TARGET_FILE:tgt> [1] will be replaced with the full path of the target.
