 The driver stack comes with a CMake based build system. A toolchain file is
 provided for reference how to cross compile for an Aarch64 based system.
 
+Note that if your host system provides cross compilers and libraries of newer
+versions than what is supported on your target system, you might be required to
+download an older version of compilers and toolchains for your target system.
+While out of scope for this README, an example
+[toolchain file](cmake/toolchain/aarch64-linux-gnu-custom.cmake) is provided to
+show what it could look like. Another option is to run a Docker image of an
+appropriate Linux distribution suited to build for your needs.
+
 Building the kernel modules requires a configured Linux kernel source tree. How
 to download and configure the Linux kernel goes beyond the scope of this readme.
 Please refer to the Linux kernel official documentation.
