# Creates and names a library, sets it as either STATIC

# You can define multiple libraries, and CMake builds them for you.
# Gradle automatically packages shared libraries with your APK.

# 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.
