I have added "gtest" to my IMAGE_INSTALL setup for the image I am creating. I then run "bitbake <my-image> -c populate_sdk" and execute the resulting script to unpack the SDK.
This all seems to work properly. The resulting SDK contains a .../usr/include/gtest with the header files I would expect for building gtest applications. However, I am not finding the gtest source anywhere. For example, I would expect there to exist in the SDK a .../usr/src/gtest/src that contains files such as gtest_main.cc.
Has anyone run into this sort of problem? Is there some way I can manipulate the recipes to force the the gtest "src" folder to be copied into the sdk properly?
