Re: cmake-based project with system lib dependency

Hi Sergey,

Hi there.
I want to configure the cmake-based project with dependency on library
The latter is located under util-linux and populated in my

util-linux-dev armv7vet2hf_neon 2.35.1 (here should be header as well and
static library)
util-linux-uuidd armv7vet2hf_neon 2.35.1 (i believe the only library)
My bb file is:

SUMMARY = "Recipe to build the 'helloworld-cpp-direct-compile' in cpp"
SECTION = "common_templates"

SRC_URI = "file://CMakeLists.txt \
file://foo.cpp \
file://foo.h "
DEPENDS = "util-linux"

(DEPENDS is for build time dependencies and you add the recipe providing
the sources for it, RDEPENDS_${PN} is for runtime dependencies and you
add packages to it (it is common to have the same name for the recipe and
the main package built by it)).

inherit pkgconfig cmake

S = "${WORKDIR}"
OECMAKE_GENERATOR = "Unix Makefiles"
# project version seems to not be propagated properly

while my CMake file has:

pkg_check_modules(uuid REQUIRED IMPORTED_TARGET "uuid >= 2.25")

Now I obtain the error from cmake:
-- Checking for module 'uuid >= 2.25'
-- No package 'uuid' found
CMake Error at

What philosophy of yocto to make it work? In other words where 'stage' is
supposed to be located so pkgconfig will find library?
I can suggest watching/listening to Live Coding sessions done by Josef
available on Yocto project's Youtube channel:

It should help you get started and understand the basics.
