Summary0015134: add_subdirectory() fails when CMakeLists.txt in drive root
DescriptionI'm using the "subst" command on windows to make my build folder the root of a separate drive. Thus, the cmake file being processed is called "N:\CMakeLists.txt". CMake then fails to process the file, with several errors, all following the pattern:

CMake Error at N://CMakeLists.txt:66 (add_subdirectory):
  add_subdirectory not given a binary directory but the given source
  directory "N:/lib/jsoncpp" is not a subdirectory of "N:/". When specifying
  an out-of-tree source a binary directory must be explicitly specified.

CMake Error at N://CMakeLists.txt:76 (get_property):
  get_property DIRECTORY scope provided but requested directory was not
  found. This could be because the directory argument was invalid or, it is
  valid but has not been processed yet.

The very same cmake file, when used in a subfolder, works without a problem.
For your reference, the CMakeLists.txt file being used is this one:
https://github.com/mc-server/MCServer/blob/562b2d1d1de7438bc763d778b56b0743affd1b5b/CMakeLists.txt [^]
Cmake is being called as:
cmake -G "Visual Studio 9 2008" .
Steps To ReproduceUse subst to map a folder containing a project to a separate drive letter. Then use CMake in that drive's root to configure the project. CMake fails with the specified error.
