Hi Johny,
I've experienced the same problem and unfortunately, I think there's no way to
set them permanently. The reason seems to
be that cmake invokes subshells for most of the commands, so the change of the
environment variable only happens in the
subshell and never reaches the parent.
I worked around this problem by executing a little script just before executing
the command which needs the environment
variables, like this:
add_custom_command(OUTPUT some_output.h
COMMAND source setup_env.sh\; my_command
DEPENDS my_dependencies)
setup_env.sh contains all the export commands to set the variables.
Hope that works for you
cheers
Gerhard
