Hi @mukesh-2538, Cmake supports specifying the cross-compiler toolchain through the CMAKE_TOOLCHAIN_FILE variable that you can pass in the Cmake configuration command (as cmake -S . -B build -DCMAKE_TOOLCHAIN_FILE=<path/to/toolchain/file>.cmake).

An example toolchain file for an ARM based Linux platform can be seen in the CMake documentation here.

I am getting the following error.

cmake -S . -B build -DCMAKE_TOOLCHAIN_FILE=/home/mukesh/trail/sercom.cmake
CMake Error: The source directory "/home/mukesh/trail/aws-iot-device-sdk-embedded-C/build" does not exist.
Specify --help for usage, or press the help button on the CMake GUI.
