[CMake] Add support for cross compiling to VxWorks

[Kuhl, Brian]

Adding the library path to CMAKE_FIND_ROOT_PATH  did not help :(

SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH C:/git/vx7-ux-ports/workbench-4/workspace/VSB64/usr/root C:/git/vx7-ux-ports/workbench-4/workspace/VSB64/usr/libcommon  C:/git/vx7-ux-ports/workbench-4/workspace/VSB64/usr/libcommon/PIC )

Hello,

please have a look at some other toolchain file like the BlackBerry one:

I guess you should set these variables:

Hope that helps,
