Can you check out the \zephyr\samples\application_development\external_lib sample project, and check the CMakeLists.txt file to see how you can add external libraries with the add_library function as you need to do that as well in addition to add the header files. What is the first error you see when trying to build this application? Usually the topmost one will give you an indication of what the root issue is.

Best regards,

Simon

I think the toolchain.h file you're looking for is located in ...\zephyr\include\zephyr. Try to also add CONFIG_NEWLIB_LIBC to your prj.conf fileto enable the use of non-minimal C functionality.
