Make - opencv

Jeg forsøger at compile et lille testprogram til opnecv, en får flg fejl undervejs:

make -C skeleton
make[1]: Entering directory `/root/Desktop/lab/skeleton'
gcc -lopencv -lhighgui skeleton.c -o skeleton
skeleton.c:6:51: error: cv.h: No such file or directory
skeleton.c:7:54: error: highgui.h: No such file or directory
skeleton.c:12: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token
skeleton.c:13: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token
skeleton.c: In function ‘main’:
skeleton.c:25: error: ‘img0’ undeclared (first use in this function)
skeleton.c:25: error: (Each undeclared identifier is reported only once
skeleton.c:25: error: for each function it appears in.)
skeleton.c:26: error: ‘img’ undeclared (first use in this function)
make[1]: *** [skeleton] Error 1
make[1]: Leaving directory `/root/Desktop/lab/skeleton'
make: *** [all] Error 2

Nogle der ved hvad jeg gør galt ??

På forhånd tak
