shell-independent way. Maybe there's a way to execute the `hostname`

Ok, I see now. HOSTNAME is a shell variable, but not an environment
variable. Check this thread here:
http://lists.freebsd.org/pipermail/freebsd-questions/2004-July/052424.html
So, is there another way I could get the hostname in CMake?
I would do what was suggested and call 'hostname' with EXECUTE_PROCESS()
(see cmake documentation).
Thanks, that works, but the OUTPUT_VARIABLE has a trailing \n. How can
I get rid of it?
Try using a string replacement or the OUTPUT_STRIP_TRAILING_WHITESPACE
argument to EXECUTE_PROCESS:
################################################3
### Run with cmake -P hostname.cmake
EXECUTE_PROCESS( COMMAND hostname
OUTPUT_VARIABLE myhostname
)
MESSAGE("myhostname = \"${myhostname}\"")
STRING(REPLACE "\n" "" new_hostname ${myhostname})
MESSAGE("new_hostname = \"${new_hostname}\"")
# Or use the handy dandy OUTPUT_STRIP_TRAILING_WHITESPACE argument
# to EXECUTE_PROCESS
EXECUTE_PROCESS( COMMAND hostname
OUTPUT_VARIABLE myhostname2
OUTPUT_STRIP_TRAILING_WHITESPACE
)
MESSAGE("myhostname2 = \"${myhostname2}\"")
####################################################
