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.
The tar should be in the "${WORKDIR}/git" directory but it will not work as you don't tell bitbake to unpack it.

You repository with tag "v0.1" contains only a README.md!

The common use case is to put all sources into the git repository. Why you want to save a tar in a git repository?


--> If I remove tar and keep just source file and CMakeLists.txt, then also it is not getting downloaded.
Have you check the content of the /home/siguser/yocto/build/tmp/work/armv7a-vfp-neon-poky-linux-gnueabi/cameracapture-0.1-r0/git directory?

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.
        ^^^
Are you sure you have change the S variable? The error still reference the common directory ("${WORKDIR}/${PN}-${PV}").

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

Do I need to set CXX Compiler in my CMakeLists.txt?
No, this are subsequent errors of the missing toolchain.cmake.

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} )
This looks okay.
