# Run test suite on a remote machine over ssh (Issue 310).
#
# Setup requirements:
# * Install rsync and ssh on local host, rsync and sshd on remote host
# * Set up RSA-key passwordless login to avoid repeatedly typing your
#   password
# * For a remote Windows host, cygwin sshd is assumed, and cygpath must be
#   on the path.  Also, make sure the USERPROFILE env var is set in your
#   ~/.bash_profile file as it doesn't seem to be set by default like it is
#   with normal Windows login.  E.g.:
#     if [ ! -n "$USERPROFILE" ]; then
#         export USERPROFILE="E:\Documents and Settings\derek"
#     fi
#
# Required parameters:
#   HOST:STRING          = Name of remote host.
#   REMOTE_WINDOWS:BOOL  = Whether remote host is Windows.
#
# Optional parameters (defaults will typically work):
#   USER:STRING           = Username on remote host.  Default is $USER from env.
#   LOCAL_SRCDIR:PATH     = Path to source dir on local machine.
#                           Default is parent dir of this script's path.
#   REMOTE_SRCDIR:PATH    = Path to source dir on remote host.
#                           Default is "~/dr/regression/src"
#   REMOTE_TESTDIR:PATH   = Path to build dir on remote host.
#                           Default is "~/dr/regression/build"
#   REMOTE_CTEST:FILEPATH = Path to ctest on remote host.
#                           Default assumes "ctest" is on the path.
#
# Examples of usage:
#
#   cd /my/checkout && cmake -DHOST=dr-ubuntu -P suite/runsuite_ssh.cmake
#
#   cmake -DHOST=mylaptop -DUSER=derek -DREMOTE_WINDOWS=ON -P /my/checkout/suite/runsuite_ssh.cmake

# we need CMAKE_CURRENT_LIST_FILE, not sure when added,
# but everyone should be using at least 2.6
