Android Studio - CMake Error: CMake was unable to find a build program corresponding to "Ninja". CMAKE_MAKE_PROGRAM is not set

I'm going crazy with this error. I have tried searching and changing my code according to some suggestions that can be found in stackoverflow but still get the same error. I have downloaded CMake and there's Ninja in it. There's no LLDB.

My Ninja's path inside CMake

My Android Studio SDK Tools

Here's the build.gradle. The comments are what I've tried

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.example.opencv"
        minSdkVersion 21
        targetSdkVersion 27
        ...
        externalNativeBuild {
            cmake {
                cppFlags ""
                //cppFlags "-frtti -fexceptions"
//                arguments "-DOpenCV_DIR=" + project(':opencv').projectDir + "/native/jni",
//                        "-DANDROID_STL=c++_shared",

                arguments "-GAndroid Gradle - Ninja"
            }
        }

    }

--- EDIT CMakeList.txt --- [Sorry. Turns out I deleted too much because of the limit...]

And here's CMakeList.txt

cmake_minimum_required(VERSION 3.4.1)


add_library( # Sets the name of the library.
             native-lib

             # Sets the library as a shared library.
             SHARED

             # Provides a relative path to your source file(s).
             src/main/cpp/native-lib.cpp )


find_library( # Sets the name of the path variable.
              log-lib

              # Specifies the name of the NDK library that
              # you want CMake to locate.
              log )

# Specifies libraries CMake should link to your target library. You
# can link multiple libraries, such as libraries you define in this
# build script, prebuilt third-party libraries, or system libraries.

target_link_libraries( # Specifies the target library.
                       native-lib

                       # Links the target library to the log library
                       # included in the NDK.
                       ${log-lib} )

Am I missing something? I really appreciate your help.

Your CMake file looks dismantled; nothing will build successfully by using it in this state. Typically for NDK projects, I've seen template CMakeLists.txt files containing CMake code for the native-lib and log-lib libraries. This template is a good place to start.

To get you half-way there, consider changing your CMake code to the following, or switching to use the template laid out in this tutorial:

cmake_minimum_required(VERSION 3.4.1)

# Specify the 'native-lib' library
add_library(native-lib SHARED src/main/cpp/native-lib.cpp)

# Find the log NDK library.
find_library(log-lib log)

# Link the log library to the native-lib library.
target_link_libraries(native-lib ${log-lib})

I recommend spending some time to get familiar with CMake, and how to construct basic CMake files. The tutorials in the cmake tag info has lots of helpful info.

In order to make ninja work you need to all before the -G parameter the following DCMAKE_MAKE_PROGRAM path .

Below is the full batch script you can use.

cmake -DBUILD_SHARED_LIBS=1 -DCMAKE_TOOLCHAIN_FILE=C:\Users\Aeon\AppData\Local\Android\Sdk\ndk\21.3.6528147\build\cmake\android.toolchain.cmake -DANDROID_NDK=C:\Users\Aeon\AppData\Local\Android\Sdk\ndk\21.3.6528147 -DCMAKE_MAKE_PROGRAM=C:\Users\Aeon\AppData\Local\Android\Sdk\cmake\3.10.2.4988404\bin\ninja.exe -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_FLAGS=-std=c++11 -frtti -fexceptions -DANDROID_ABI=arm64-v8a -DANDROID_PLATFORM=android-16 -DANDROID_TOOLCHAIN=clang -DANDROID_STL=c++_shared -DANDROID_CPP_FEATURES=rtti exceptions "C:\DLib"
