In Unix shell we can do that:

This way the environment variable is only set in the environment of the

"export" built-in.
I would like to be able to do the same for a custom command in CMake.
Ideally I was looking for something like that:
add_custom_command(
OUTPUT out
COMMAND cmd in out
DEPENDS in
ENVIRONMENT VAR foo
)
Any idea?
Well, if you only care about UNIX you can always use /bin/env :-).
I'm not sure if build tools on Windows are able to support setting
environment variables. If you need to do it portably (and can't use the
code Brad mentioned), you may need to use cmake's -P mode with a script
that wraps your command (using execute_process) after first setting up
the desired environment.
