I tried using the 'externallib' sample with toolchain 2.7.0 and SDK 2.6.1, and it works fine.
However, if I add something like #include <zephyr/kernel.h> in 'mylib.h', the compiler throws an error.
I have tried including the Zephyr library directories, adding a CMakeLists.txt along with the 'Makefile', but I was
unable to get the compilation to work. In my external library, I actually need to include some parts of the Zephyr libraries as well.
examples:
PREFIX ?= .
OBJ_DIR ?= $(PREFIX)/obj
LIB_DIR ?= $(PREFIX)/lib
