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
<http://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.
You shouldn't need a do_install as cmake install the binary.

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:

It looks as something went wrong. Please clear the old package and
try again or increment the PR number.

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.
