I am getting this error while building project. Trying to add a new library in android-studio. Is there anybody who has an idea basically I am trying to create a new library here.

Options tried:

1. Manually deleted build
2. Invaildate cache/restart
3. Gradle clean build cache
4. Build->Clean Project

But build is failing.

Source C:\Users\abc\AndroidStudioProjects\Events\app\build\intermediates\cmake\debug\obj\armeabi-v7a\libnative-lib.so and destination C:\Users\abc\AndroidStudioProjects\Events\app\build\intermediates\cmake\debug\obj\armeabi-v7a\libnative-lib.so must be different

CMakeLists.txt I am using for the same:

```
# For more information about using CMake with Android Studio, read the
# documentation: https://d.android.com/studio/projects/add-native-code.html

# Sets the minimum version of CMake required to build the native library.

cmake_minimum_required(VERSION 3.4.1)

# Creates and names a library, sets it as either STATIC
# or SHARED, and provides the relative paths to its source code.
# You can define multiple libraries, and CMake builds them for you.
# Gradle automatically packages shared libraries with your APK.

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).
             native-lib.cpp
        )

add_library (
        testLib
        SHARED
        TestClassesManager.cpp
)
# Searches for a specified prebuilt library and stores the path as a
# variable. Because CMake includes system libraries in the search path by
# default, you only need to specify the name of the public NDK library
# you want to add. CMake verifies that the library exists before
# completing its build.

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}

        )

target_link_libraries(
        testLib

        native-lib
)

```

The error goes away if I am replacing 

```
target_link_libraries(
        testLib

        native-lib
)

```

by 

```
target_link_libraries(
        testLib
    ${log-lib}

)

```

But I want to link both libraries. But it is giving above error. Please help.
