[cmake-developers] [PATCH 3/3] FindQt4: document cross compilation

[Clinton Stimpson]

Hi Pascal,

Thanks for the patches.

Can you share with us why setting CMAKE_FIND_ROOT_PATH does not work, or how 
this new method compares?

For example, in the toolchain file:
SET(CMAKE_FIND_ROOT_PATH  /path/to/Qt ...)
