I am trying to compile a CMake project for android.
I use QtCreator to create and compile the project. Using QMake works fine, but CMake projects don't work.
CMake Project parsing failed.

CMake Project parsing failed.
I found several posts about this, but most of them were not answered or simply not useful. I found this helpful, so I added
SET (CMAKE_C_COMPILER_WORKS 1)
SET (CMAKE_CXX_COMPILER_WORKS 1)
before project(). But now I get
CMake Error in CMakeLists.txt:
No known features for CXX compiler
"Clang"
version 8.0.2.
CMake Project parsing failed.
So far I haven't found something useful for that.
I hope I can get some more help this way.
ps: I recently reinstalled my os (Windows 10), so if I forgot to update something it's not older than two month. I let QtCreator, Visual Studio and Android Studio do the installation of the toolchains.
pps: The project is a new project created by QtCreator

I am trying to use CMake to create a .so library that uses OpenCV for use on Android.
I have no prior experience with CMake before this. I got a couple things working with CMake so far. I successfully built and ran a simple OpenCV program for windows and I've also created a .so file that doesn't use OpenCV. I was able to successfully called that .so from a Unity program on Android. My goal is to create an OpenCV plugin for Unity. I turned to CMake because I tried making a simple .so in Visual Studios, but my Unity program couldn't find it (though I was able to create a .dll that used OpenCV for a windows Unity program using Visual Studios that worked).
I have both r19c Android NDK and OpenCV 4.5.2 Android SDK on my C drive.
My code file is test.cpp, and it very simply uses some OpenCV elements. It's as follows:
#include "opencv2/opencv.hpp"
extern "C" int get_number()
{
cv::Mat img(2,2, CV_8UC3, cv::Scalar(126,0,255));
cv::Size size = img.size();
int width = size.width;
return width;
}
I am thinking that my error may be in the CMakeLists.txt file, that I am probably pointing to the wrong OpenCV folders.
My CMakeLists.txt is:
cmake_minimum_required(VERSION 3.20)
set(OpenCV_DIR C:/OpenCVAndroid/sdk/native/jni/abi-arm64-v8a)
set(OpenCV_INCLUDE_DIRS C:/OpenCVAndroid/sdk/native/jni/include)
project( test )
find_package( OpenCV REQUIRED )
include_directories( ${OpenCV_INCLUDE_DIRS} )
add_library( test SHARED test.cpp )
and I'm using a .bat file that has the following lines:
rmdir /s /q build
mkdir build
cd build
"C:/Program Files/CMake/bin/cmake.exe" ^
-S=C:\Users\m_knu\Desktop\test ^

pause
all three files are located in the same folder.
When I run the .bat file I get the following output:

As I mentioned earlier, my guess is that I've incorrectly referenced the OpenCV directories, but I wouldn't be surprised if I'm missing other things.
I have project that recently start using ndk. I have CI worked with Docker. After adding ndk to my project I added ndk to docker file, however for now I see problem with Ninja version.
Here's log output

CMake Error:

Qt does not support a recent version of NDK, in the docs it is recommended to use NDK 10e
Did anyone implemeted Cricket audio engine (http://www.crickettechnology.com/blog/) for Android Studio using gradle and Cmake (Android NDK) ?
I have imported the lib in my Cmake like this:
target_link_libraries(test
${CMAKE_CURRENT_SOURCE_DIR}/../../test/cricketaudio/lib/libck.a)
And the compiler sees it alright but when I try to run it, the linker gives me this error:

I am aware that libck (cricket audio) has a dependency lib the Android NDK cpufeauters lib which is located in the Android NDK bundle (Android\Sdk\ndk-bundle\sources\android\cpufeatures).
I don`t know how to make this cpufeatures lib visible to the Linker of my project ???
Any help or pointers would be appreciated.
I have simply included the cpu-features.c and header file to my cmakelist and now it works :).

I think you need to install compiler driver of c++.
