[oe] [PATCH] render cmake search path stricter

[Douglas Royds]

Any particular reason not to include CMAKE_FIND_ROOT_PATH_MODE_PACKAGE?

Normally this won't have any effect, as CMake will look in the CMake 
installation for FindSomething.cmake ("module" mode). But if a package 
installs a SomethingConfig.cmake in /usr/share/cmake (the "config" mode 
of find_package) we should be looking only in staging, not trawling 
around on the host PC.
