Hi Stefan, Hi all, My build was successful with CMake. I made some changes to my recipe:
DESCRIPTION = "cameracapture application" SECTION = "examples" LICENSE = "CLOSED" PR = "r0" DEPENDS = "opencv" SRC_URI = "git://github.com/zafrullahsyed/cameracapture.git ;protocol=https;tag=v0.1" S = "${WORKDIR}/git" inherit pkgconfig cmake do_install() { install -d ${D}${bindir} install -m 0755 cameracapture ${D}${bindir} } I didn't specify do_install, which caused the errors. Your inputs helped me very much. Thanks a ton.
