    You can opt to use the FreeRTOS CMSIS implementation provided by the Cube repository by supplying
    `USE_CMSIS_RTOS=ON` or `USE_CMSIS_RTOS_V2` to CMake.
 
+The `lwip` support does not have a dedicated example because most STM devices have different PHYs
+and/or there is machine and linker script specific code which makes it difficult to create a

 First of all you need to configure toolchain and library paths using CMake variables. There are

+[cmake/FindLwIP](cmake/FindLwIP.cmake) - finds LwIP sources in STM32Cube repository and format them
+as `IMPORTED` targets. This requires a `lwipopts.h` in the application include path to work.
+If the Netconn or Socket API is used, the CMSIS support needs to be linked like specified in

+Available LwIP libraries:
+
+* `LwIP::IPv4` - IPv4 support
+* `LwIP::IPv6` - IPv6 support
+* `LwIP::SYS` - System support (`sys_arch.c`)
+* `LwIP::API` - Support for Netconn and Socket API. Will also link `LwIP::SYS` automatically
