 It is also possible to build the unit test with Cmake. The binaries can then be used with another test platform, e.g. Fastmodel.
 In this case note that toolchain, linker file and Uart code need to be provided. See externs in Retarget.c for specific Uart functions.

-Example:
+UART and LINK_FILE have default values but you most probably need to replace them unless you place your code relatively to the default paths.
