[CMake] CMAKE_PROJECT_NAME

[Josef Karthauser]

Isn't the value of CMAKE_PROJECT_NAME supposed to contain the name given
to the last PROJECT() call?  It appears with the current version of
CMAKE that it gets the value of the first call to PROJECT, and isn't
subsequently updated.

For example:

    CMakeLists.txt:
	Project(foo)
	MESSAGE(${CMAKE_PROJECT_NAME})

	Project(bar)
	MESSAGE(${CMAKE_PROJECT_NAME})

Outputs:

    foo
    foo

when run.
