[cmake-developers] find_program() not using PATH on Windows?

[Robert Dailey]

So I have Git 2.11.1 installed and it's located in E:\Git\cmd\git.exe.
I ticked the option in the installer to add it to path.

I tried using the FindGit module via find_package() to find Git, but
it's not working. So I tried a simpler case:

find_program(GIT_EXECUTABLE git)

However it cannot find 'git'. No matter if I specify PATHS either, it
won't work. The documentation states it should use PATH at some point
to find git.exe, but it doesn't seem that it is doing this.

My PATH on Windows is as follows:

$ echo %PATH%
C:\Program Files\ConEmu\ConEmu\Scripts;C:\Program
Files\ConEmu;C:\Program
Files\ConEmu\ConEmu;C:\ProgramData\Oracle\Java\javapath;C:\windows\system32;C:\windows;C:\windows\System32\Wbem;C:\windows\System32\WindowsPowerShell\v1.0\;C:\Program
Files\Beyond Compare
4;E:\ant\bin;E:\android\sdk\tools;E:\android\sdk\platform-tools;E:\code\ziosk-scripts\device-scripts;E:\tools\ninja;E:\Ruby22\bin;E:\Python35;E:\Python35\Scripts;E:\Program
Files\CMake\bin;E:\Program Files\CMake\bin;C:\Program Files
(x86)\Notepad++;E:\Git\cmd;C:\Program Files (x86)\Windows
Kits\8.1\Windows Performance Toolkit\;C:\Program Files (x86)\Microsoft
Emulator Manager\1.0\;C:\Program
Files\TortoiseSVN\bin;C:\Users\robert\AppData\Local\Microsoft\WindowsApps

Note that "E:\Git\cmd" is in the list of paths. I'm able to run
git.exe commands from CMD as well.

Any idea why CMake is not finding git.exe? I'm using CMake v3.8.0-rc2.
