platform-rpipico missing version.c

[cuu]

commit hash : d0ae49739d924e0ae0759d7cae661aa82ba289ca

when I try to build platform-rpipico

cmake shows

CMake Error at CMakeLists.txt:27 (add_executable):
  Cannot find source file:

    ../../version.c

well I can not find version.c anywhere

where is the verison.c ?

Thanks
