Help: Document behavior of if(EXISTS,IS_DIRECTORY) for empty paths
Document and add explicit tests for empty string input:
`if(EXISTS "")` and `if(IS_DIRECTORY "")` are always false.
This avoids need for users to do extra checks due to
CMake non-short-circuit logic as below:
if("${p}")
if(EXISTS "${p}")
