[yocto] Trouble with yocto sdk in collaboration with eclipse and cmake

[Hartwig, Guido]

Hi,
I have some trouble with the yocto sdk in collaboration with eclipse and yocto CMake project. 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:

..
CMake Error at /usr/share/cmake-2.8/Modules/CMakeTestCCompiler.cmake:61 (message): The C compiler
 "/opt/puck/1.0.0/sysroots/x86_64-pucksdk-linux/usr/bin/arm-kostal-linux-gnueabi/arm-kostal-linux-gnueabi-gcc"
  is not able to compile a simple test program
...

This error occurs because the compiler is called with the wrong flags.
The SDK environment-setup script export the following environment variables
export CC="arm-kostal-linux-gnueabi-gcc  -march=armv7-a -marm -mfpu=neon  -mfloat-abi=hard -mcpu=cortex-a8 --sysroot=$SDKTARGETSYSROOT"
export CFLAGS=" -O2 -pipe -g -feliminate-unused-debug-types -fdebug-prefix-map=/home/hartwig02/Workspace/build-puck/build/tmp/work/x86_64-nativesdk-pucksdk-linux/meta-environment-scb/1.0-r8=/usr/src/debug/meta-environment-scb/1.0-r8 -fdebug-prefix-map=/home/hartwig02/Workspace/build-puck/build/tmp/sysroots/x86_64-linux= -fdebug-prefix-map=/home/hartwig02/Workspace/build-puck/build/tmp/sysroots/x86_64-nativesdk-pucksdk-linux= "

The eclipse environment (set by the yocto plugin) shows the following environment:
CC = arm-kostal-linux-gnueabi-gcc  -march=armv7-a -marm -mfpu=neon  -mfloat-abi=hard -mcpu=cortex-a8 --sysroot=/opt/puck/1.0.0/sysroots/cortexa8hf-neon-kostal-linux-gnueabi
CFLAGS =  --sysroot=/opt/puck/1.0.0/sysroots/cortexa8hf-neon-kostal-linux-gnueabi
OECMAKE_C_COMPILER = arm-kostal-linux-gnueabi-gcc
OECMAKE_C_FLAGS =    --sysroot=/opt/puck/1.0.0/sysroots/cortexa8hf-neon-kostal-linux-gnueabi

I assume that yocto cmake uses the OECMAKE* variables to build the program. 
The error occurs because the following compiler options (Tunes) are missing "-march=armv7-a -marm -mfpu=neon  -mfloat-abi=hard -mcpu=cortex-a8"

Now my questions
1.	Is it right that the yocto plugin cuts off the tunes from the OECMAKE_C_COMPILER?
2.	Is there a reason that this compiler options are not appended to the CFLAGS?

Thank you for your help
