[yocto] bitbake with cmake recipe

[Zafrullah Syed]

Hi Stefan,

I updated 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

I have my source file and CMakeLists.txt as tar on github. tar is not
getting downloaded.

--> If I remove tar and keep just source file and CMakeLists.txt, then also
it is not getting downloaded. I am getting

CMake Error: The source directory
"/home/siguser/yocto/build/tmp/work/armv7a-vfp-neon-poky-linux-gnueabi/cameracapture-0.1-r0/cameracapture-0.1"
does not appear to contain CMakeLists.txt.

--> I copied my CMakeLists.txt file in ${WORKDIR}/git and tried the build,
got this following error:

ERROR: Function failed: do_configure (see
/home/siguser/yocto/build/tmp/work/armv7a-vfp-neon-poky-linux-gnueabi/cameracapture-0.1-r0/temp/log.do_configure.10784
for further information)

cameracapture_0.1.bb, do_configure) failed with exit code '1'

Do I need to set CXX Compiler in my CMakeLists.txt?

My CmakeLists.txt file:

cmake_minimum_required(VERSION 2.8)
project(cameracapture)
find_package( OpenCV REQUIRED )
add_executable( cameracapture cameracapture.cpp )
target_link_libraries( cameracapture ${OpenCV_LIBS} )

Can you please give me some inputs?

Thanks & Regards,
