Summary:                    CMake can't always find git.exe in PATH element with
quotation marks
Description: 
My 581-character path includes things in c:\Program Files, some but not all in
quotation marks. The element of the USER variable of PATH pointing to git.exe
had quotation marks around it and sometimes that prevented cmake from finding
it. Removing the quotation marks solved the problem. Their presence does not
invalidate the path as far as cmd.exe is concerned: it found git.exe just fine
either way, so this is an issue, if a minor one, easily worked around.

For a "simple" CMakeLists.txt file this problem never occurred!!?


Steps to Reproduce: 
When my PATH variable contained:

set
PATH=C:\Perl64\site\bin;C:\Perl64\bin;C:\Python27\;C:\Python27\Scripts;C:\ProgramData\Oracle\Java\javapath;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program
Files\TortoiseSVN\bin;C:\Program Files (x86)\Windows Kits\8.1\Windows
Performance Toolkit\;C:\Program Files\Microsoft SQL
Server\110\Tools\Binn\;C:\Program Files (x86)\Microsoft
SDKs\TypeScript\1.0\;C:\Program Files\Common Files\ThinPrint\;C:\Program
Files\TortoiseGit\bin;e:\me\tools;"c:\Program
Files\Git\cmd\";%APPDATA%\Python\Scripts;C:\Program Files (x86)\CMake\bin

A three-line CMakeLists.txt file like this:

cmake_minimum_required( VERSION 3.1 )

find_package( Git )

message( "Returned value of GIT_EXECUTABLE is ${GIT_EXECUTABLE}" )

was able to find Git but calling find_package( Git ) from a more complex
CMakeLists.txt (that includes other sub-CMakeLists files) failed, even from the
first line of the most top-level CMakeLists.txt file, even when the "message()"
call was followed by a "return()".

This persisted until I removed the quotation marks from the path. This occurred
even if I moved the "git" path to the front of the PATH variable.
