Thanks Ross,

Here is the error message when trying to build sdk-dslink-c within Yocto  Dizzy version.

Here  is part of the CMakeList.txt for sdk-dslink-c that required the minimum version:

cmake_minimum_required(VERSION 3.0.0 FATAL_ERROR)
project(sdk_dslink_c C)

option(USE_CCACHE "Enable CCache Support" ON)

option(DSLINK_BUILD_EXAMPLES "Whether to build the examples" OFF)
option(DSLINK_TEST "Whether to enable tests" OFF)
option(TOOLCHAIN_DYNAMIC_LINK_ENABLE "Enable Dynamic Linking for Toolchain" ON)

##### Configure CMake Modules #####

set(CMAKE_MODULE_PATH ${CMAKE_CURRENT_LIST_DIR}/tools/cmake)

include(MacroEnsureOutOfSourceBuild)
ensure_out_of_source_build("Please do not build the C SDK inside the source directory.")

##### Check Configuration #####

if ("${CMAKE_GENERATOR}" STREQUAL "Ninja" AND DSLINK_TEST)
    message(WARNING "C SDK Unit Tests are currently not supported under Ninja.")
    set(DSLINK_TEST OFF)
endif()

Thanks

Our SDK has the Yocto Project 1.7 Dizzy version and it supports cmake 2.8.12 version as show below:
./meta/recipes-devtools/cmake/cmake_2.8.12.2.bb<http://cmake_2.8.12.2.bb>
./meta/recipes-devtools/cmake/cmake-native_2.8.12.2.bb<http://cmake-native_2.8.12.2.bb>

We need to pulling the cmake 3.x.x version for our sdk-dslink-c recipe build.

I found  git://git.openembedded.org/openembedded-core<http://git.openembedded.org/openembedded-core> has version  3.6.x
So I tried to pull it in. But this version got a trace back when integrated to our SDK Yocto Dizzy.

Can you advise which open embedded-core version/git location to pull in to SDK Dizzy version for cmake 3.x.x version

There is no official dizzy recipe for cmake 3.  If you share what the error is, then we may be able to help backporting the recipe to dizzy.
