Proyecto de compilación cruzada de opencv en Ubuntu para Raspberry Pi
Estoy luchando con esto durante 2 días y no logro que funcione.
Lo que he hecho hasta ahora:
OpenCV 2.4.8 construido desde la fuente en Ubuntu 12.04 LTS -> Los proyectos OpenCV compilan y ejecutan en Ubuntu
OpenCV 2.4.8 construido desde la fuente en Raspberry Pi Raspian -> Los proyectos de OpenCV compilan y ejecutan en Raspberry Pi
construyó un compilador cruzado para Raspberry Pi con crosstools-ng (http://www.bootc.net/archives/2012/05/26/how-to-build-a-cross-compiler-for-your-raspberry-pi/) -> Los programas c ++ creados en Ubuntu con el compilador cruzado se ejecutan en la Raspberry Pi
¿Cuáles son mis problemas?
Los programas OpenCV no compilan con el compilador cruzado|2|fatal error: opencv2/highgui/highgui.hpp: No such file or directory|
# this one is important
SET(CMAKE_SYSTEM_NAME Linux)
#this one not so much
SET(CMAKE_SYSTEM_VERSION 1)

SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
con esta cadena de herramientas intenté cruzar compilar OpenCV con este comando:
cmake -DCMAKE_TOOLCHAIN_FILE=../Toolchain-RaspberryPi.cmake ../
Después del comando make se compila hasta el 27%. Ahí se detiene con este error.

||More errors follow but not being shown.|
||Edit the max errors limit in compiler options...|
||=== Build finished: 50 errors, 29 warnings ===|
Entonces mi pregunta es:
¿Cómo puedo obtener un crosscompiler en ubuntu para trabajar con opencv? Solo quiero compilar en ubuntu, copiar el programa en el Pi y ejecutarlo allí.
Muchas gracias
