Cmake with bitbake recipe - cmake

Question

I am trying to build an yocto image with my own package. I have OpenCV code on github which uses cmake.
I trying to write a recipe for it and facing lot of errors. Can any one give some hints on what functions or parameters to include in my recipe. My recipe looks as following
DESCRIPTION = "cameracapture application"
SECTION = "examples"
LICENSE = "CLOSED"
PR = "r0"
DEPENDS += "opencv"
SRC_URI = "git://https://github.com/zafrullahsyed/cameracapture.git;protocol=https;tag=v0.1"
EXTRA_OECMAKE=""
do_configure() {
cmake ../
}
inherit pkgconfig cmake
I followed these tutorials to write my recipe with cmake but in vain:
Bitbake Player recipe
Cmake-Bitbake-QT

Answer 1

The correct way of writing own recipes with cmake as follows:
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}
}
Previously I didn't add do_install that's the reason yocto downloads the recipe but unable to include it Image.

Answer 2

If the CMakeLists.txt uses the install command then bitbake will do the install for you and you won't need to define you own do_install.
install(TARGETS cameracapture DESTINATION bin)

Answer 3

add the source directory in your recipe.
example
S = "${WORKDIR}/cameracapture
S is the source code path where your CMakeList.txt.
any how your are inheriting the cmake bbclass in your recipe, so it will take care of all configure , compile and install functionalities.
after doing this you can remove you do_configure function in the above recipe also.
you can add your make options if any to the below macro (as you kept empty).
example
EXTRA_OECMAKE = "all"
