    CMake Warning (dev) in CMakeLists.txt:
      No project() command is present.  The top-level CMakeLists.txt file must
      contain a literal, direct call to the project() command.  Add a line of
      code such as

        project(ProjectName)

      near the top of the file, but after cmake_minimum_required().

      CMake is pretending there is a "project(Project)" command on the first
      line.
    This warning is for project developers.  Use -Wno-dev to suppress it.

It says that first definition is in materkeys.c.o, so i presume is the objcect file from masterkeys.c, but actually there isn't that definition in there... no clue...
