[Development] CMake && QtCreator cross-compilation for ARM fails

[Denis Shienkov]

Hi guys.

I have the Qt project, based on both QMake and QBS. This project should 
be targeted on a Apalis iMX6 board with BSP Linux, generated from Yocto. 
Also I have a Yocto SDK which is added to QtCreator (as a configured 
Kits). The QMake and QBS doing the ARM cross-compilation from the 
QtCreator like a sharm, but the CMake fails on the configure step:

"

    The ASM compiler identification is GNU Found assembler:
    /mnt/data/Yocto-miatech/sdks/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gccThe
    C compiler identification is GNU 6.4.0 The CXX compiler
    identification is GNU 6.4.0 Check for working C compiler:
    /mnt/data/Yocto-miatech/sdks/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gccCheck
    for working C compiler:
    /mnt/data/Yocto-miatech/sdks/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc —
    broken CMake Error at
    /usr/share/cmake-3.10/Modules/CMakeTestCCompiler.cmake:52 (message):

    «/mnt/data/Yocto-miatech/sdks/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-gcc»

    is not able to compile a simple test program.

    It fails with the following output:

    Change Dir:

    CMake Project parsing failed.

I tried even specify the cmake's toolcain file from the QtCreator settings:

"
CMAKE_TOOLCHAIN_FILE = 
/mnt/data/Yocto-miatech/sdks/sysroots/x86_64-pokysdk-linux/usr/share/cmake/OEToolchainConfig.cmake

"

PS: WTF? Why the Qt's management choosed the CMake's instead of QBS? 
 From my point of view, the CMake it is a crap...
I know, that I'm not a CMake expert, but Why I need to spent a lot time 
to make the CMake working wich an unknown result,
instead of just using QBS? Cross-compilation with QBS works 
immediatelly, but with CMake sucks!

This is my soul cry ... guys, what are you doing?

Denis
