Hi,  
I’m trying to build Qgroundcontrol on windows 10 using Qt 5.11 with NDK 17. When i open the qgroundcontrol.pro file, i get a warning saying:

> “C:\Users\poury\AppData\Local\Android\Sdk\ndk\android-ndk-r17c\toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86\_64\bin\arm-linux-androideabi-gcc” is used by qmake, but “C:\Users\poury\AppData\Local\Android\Sdk\ndk\android-ndk-r17c\toolchains\llvm\prebuilt\windows-x86\_64\bin\clang.exe” is configured in the kit.  
> Please update your kit (Android for armeabi-v7a (Clang Qt 5.11.0 for Android armv7)) or choose a mkspec for qmake that matches your target environment better.

And when i try to build the project, i get this error:

> linking debug\libQGroundControl.so  
> arm-linux-androideabi-g++: error: oj\moc\_CoordinateVector.obj: No such file or directory  
> make: \*\*\* [debug\libQGroundControl.so] Error 1  
> 00:29:32: The process “C:\Users\poury\AppData\Local\Android\Sdk\ndk\android-ndk-r17c\prebuilt\windows-x86\_64\bin\make.exe” exited with code 2.  
> Error while building/deploying project qgroundcontrol (kit: Android for armeabi-v7a (Clang Qt 5.11.0 for Android armv7))  
> When executing step “Make”

I tried searching for a solution but i had no luck, could somebody help me to figure this out?
