Du you know CMAKE_CROSSCOMPILING_EMULATOR?

Let’s say you want to run your tests on a Raspberry Pi via SSH.

File: run_remote.sh

#!/usr/bin/env bash
set -e

TARGET_HOST="pi@192.168.1.42"
TARGET_DIR="/tmp/cmake_test"
REMOTE_BINARY="$TARGET_DIR/$(basename "$1")"

# 1. Copy binary to remote
ssh "$TARGET_HOST" "mkdir -p $TARGET_DIR"
scp "$1" "$TARGET_HOST:$REMOTE_BINARY"

# 2. Shift script args so remaining are test arguments
shift

# 3. Run binary on remote and forward stdout/stderr
ssh "$TARGET_HOST" "$REMOTE_BINARY" "$@"

Than you my use it like this:

set(CMAKE_CROSSCOMPILING_EMULATOR
    ${CMAKE_SOURCE_DIR}/run_remote.sh
    CACHE STRING "Command to run executables on target")

add_executable(mytest test.cpp)
add_test(NAME mytest COMMAND mytest)
