[Cmake] where to find already installed default libraries

[Ian Scott]

Geoff,

You could search the following places for any installed libraries, e.g. JPEG

Registry entries
HKEY_CURRENT_USER\Software\Microsoft\DevStudio\6.0\Build
System\Components\Platforms\Win32 (x86)\Directories\Include Dirs
and Library Dirs.

The LIB and INCLUDE environment variables.

Ian.
