  Introduction
  ------------
  
  Shows a hello world example which first creates and links a static library
  
  
negative.code: This will be used to create a static library with the name libhello_library.a with
  the sources from the +library_SOURCES+ variable.
  
  ## Linking a Library
  
  When creating an executable that will use your library you must tell the compiler
  about the library. This can be done using the +target_link_library()+ function.
