cross compiling: template toolchain file

[certabitmh]

Hi,
just managed to get it cross compiled for an arm9 toolchain and wanted to share the toolchain file I've created according to https://cmake.org/cmake/help/book/mastering-cmake/chapter/Cross%20Compiling%20With%20CMake.html:
 
toolchain.cmake

# the name of the target operating system
set(CMAKE_SYSTEM_NAME Linux)
 
set(CMAKE_SYSTEM_PROCESSOR arm)
 
# which compilers to use for C and C++
set(CMAKE_C_COMPILER   arm-linux-gcc)
set(CMAKE_CXX_COMPILER arm-linux-g++)
 
# where is the target environment located
set(CMAKE_FIND_ROOT_PATH  /path/to/target-build/toolchain)
 
# adjust the default behavior of the FIND_XXX() commands:
# search programs in the host environment
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
 
# search headers and libraries in the target environment
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

build it with

cmake -DCMAKE_INSTALL_PREFIX="/path/to/install" -DCMAKE_BUILD_TYPE="Release" -DCMAKE_TOOLCHAIN_FILE=/path/to/toolchain.cmake ../aws-iot-device-sdk-cpp-v2 

cmake --build . --target install
