Including a static library in CMAKE from a different folder for an Android Project

Question

I am trying to convert my Android NDK cpp projects (ndk-build with Android.mk) to CMAKE in Android Studio. I have a project hierarchy like this:

.
├── Module1
│   ├── CMakeLists.txt
│   ├── include
│   │   └── Module1
│   ├── libModule1
│   │   ├── Module1File1.cpp
│   │   └── Module1File2.cpp
│   └── utModule1
├── MyProject
│   ├── CMakeLists.txt
│   ├── MyProject.iml
│   ├── build
│   │   ├── generated
│   │   ├── intermediates
│   │   └── outputs
│   ├── build.gradle
│   ├── proguard-rules.pro
│   └── src
│       │
│       ├── MyProjectFile1.cpp
│       └── MyProjectFile2.cpp
|
└── settings.gradle

Module1 CMakeLists.txt:

cmake_minimum_required(VERSION 3.4.1)
add_library( # Specifies the name of the library.
             Module1

             # Sets the library as a shared library.
             STATIC

             # Provides a relative path to your source file(s).
             libModule1/Module1File1.cpp
             libModule1/Module1File2.cpp )

MyProject CMakeLists.txt:

cmake_minimum_required(VERSION 3.4.1)

add_subdirectory(../MyModule1)

add_library( # Specifies the name of the library.
             MyProject
             # Sets the library as a shared library.
             SHARED
             # Provides a relative path to your source file(s).
             src/MyProjectFile1.cpp
             src/MyProjectFile2.cpp)

target_link_libraries( # Specifies the target library.
        MyProject
        # Dependencies
        MyModule1
        # Links the target library to the log library
        # included in the NDK.
        ${log-lib})

I am seeing the following error when I build:

CMake Error at CMakeLists.txt (add_subdirectory):

How do I include MyModule1 into MyProject?

Answer 1

Suggested fix from:

Add a dependency not in a subdirectory using CMake

worked for me.

include_directories(../MyMModule1/include/)
add_subdirectory("../MyMModule1/" "${CMAKE_CURRENT_BINARY_DIR}/MyModule1_build")
