CMake in populate_sdk

CMake in populate_sdk

[Benjamin Fleming]

How do I add packages to the populate_sdk option? 
I have an image (myimage) that depends on some custom packages which inherit the cmake bbclass. My expectation is that the populate_sdk task would notice that cmake is required for building and, as a result add cmake to the SDK. That is not the case. Also, for some reason, make is not included, either:

$ source /opt/poky/1.6.2/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi
$ which automake
/opt/poky/1.6.2/sysroots/x86_64-pokysdk-linux/usr/bin/automake
$ which make
usr/bin/make

What should I be adding to cause the inclusion of CMake in the SDK output?

Something like this:

Ok, adding TOOLCHAIN_HOST_TASK_append = " nativesdk-cmake" seems to work; it adds cmake to the SDK.
One more question; when building using the SDK, my cmake-based project fails to find required libraries; presumably it needs a toolchain.cmake file. Is there some way for the populate_sdk task to generate the toolchain.cmake files also? (I see that it generates something for autotools)

Thanks, Ben

We added this to gnuradio:

https://github.com/gnuradio/gnuradio/blob/master/cmake/Toolchains/oe-sdk_cross.cmake

I wonder if we could generalize this.
