Add project to cmake of example code

[TimmRuppert]

Describe the bug

Running the cmake configuration give

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.

Describe how to reproduce the bug

Freshly reconfigure your build using cmake

Describe the expected behavior

No warnings

Additional context

Simply adding project(OSMPExamples) should be sufficient.
