This probably means that the files that were missing in your first 
attempt caused invalid test results to be placed in the CMakeCache.txt 
file in your build tree.  Please start with an empty build tree and try 
the build again.

This message comes after "If you are writing a CMakeList file", so it 
only applies when authoring a new project to build with CMake.  That 
does not apply in your case.
