I have manually added the flags from CC (-march=armv7-a -marm -mfpu=neon -mfloat-abi=hard -mcpu=cortex-a8) to the OECMAKE_C_FLAGS and then it works. I try to find a way, where CMAKE works out of the Box with yocto-plugin. I think the plugin is the problem for this issue.

CFLAGS should be passed down to cmake build system. That seems to be the problem you are seeing.
