I have install all necessary eclipse plugins and linked my sdk with the yocto-plugin as described in the manual. When I try to build the "Hello World" yocto cmake project it fails with following message:

the error seems to be already fixed in the eclipse-poky repository. Commit #8315d3ec84 to luna/krogoth branch:

org.yocto.sdk.ide: Use CFLAGS from CC variable in cmake toolchain file
The CC and CXX variables imported from the Yocto build environment
may contain additional compiler flags after the compiler name. Extract
those and add them to cmake toolchain file variables, too.

This is the exact issue we have seen. Unfortunately this change has been commited after the tag for yocto-2.1 was created and so this is not released yet. After building a new version of the eclipse plugin based on the luna/krogoth branch the error mentioned above is gone.
