Compiling Opencv Projects on BeagleBoard RevC4

Hello all
I’ve installed ubuntu in my laptop and worked with opencv and compiled some projects in ubuntu (using CMake cross compiler)
some days ago I bought an beagleboard (omap3530)RevC4 AND installed angstrom with opencv library included to it , but I did not find Cmake package for compiling
my projects , do any one of you know if it is possible to compile opencv projects without installing Cmake package ?(what should I do?)
(my board is not connected to internet so I got to download the packages from my laptop and then install it using shell commands .)
one more question :
is it also possible to install ubuntu for my board , because I’ve read in some pages that ubuntu is only for beagleboard -xm and ubuntu is not supported in my board !
thanks guys.
