Cmake compiler check does not seem to take into account sysroot settings

In case I set up a compiler toolchain for a yocto distribution with the following kit configuration:
Device Type: Generic Linux Device
Sysroot: /opt/yocto/build/tmp/sysroots/baytrail_soc
Compiler: /opt/yocto/build/tmp/sysroots/x86_64-linux/usr/bin/x86_64-poky-linux/x86_64-poky-linux-gcc
Qt version: None
CMake Tool: /usr/local/bin/cmake (points to CMake 3.3.1)
CMake Generator: CodeBlocks - Unix Makefiles
CMake Configuration:
CMAKE_CXX_COMPILER:STRING=%{Compiler:Executable}
QT_QMAKE_EXECUTABLE:STRING=%{Qt:qmakeExecutable}

The cmake check for the compiler fails when trying to link the cmake compiler test application with the following error:

Running "/usr/local/bin/cmake /home/volkerv/Repos/Software '-GCodeBlocks - Unix Makefiles' -DCMAKE_CXX_COMPILER:STRING=/opt/yocto/build/tmp/sysroots/x86_64-linux/usr/bin/x86_64-poky-linux/x86_64-poky-linux-gcc -DQT_QMAKE_EXECUTABLE:STRING=" in /home/volkerv/Repos/Software/temp/baytrail_soc/Debug.

The C++ compiler
"/opt/yocto/build/tmp/sysroots/x86_64-linux/usr/bin/x86_64-poky-linux/x86_64-poky-linux-gcc"
is not able to compile a simple test program.

It fails with the following output:

The only way to get things working again is to add the following CMake configuration adjustments which bypassed the compiler check

CMAKE_CXX_COMPILER_WORKS:STRING=1

But this shouldn't be the solution. No idea what has to be passed to cmake to avoid that problem. Normally I adjust the compiler settings for cross compilation within my CMakeLists.txt files. That's why it worked in former Qt creator versions I guess. But normally it should be possible to let qt creator select all the stuff based on the kit configuration. If only it would pass at least the compiler check successfully
