# 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.

# Searches for a specified prebuilt library and stores the path as a

# you want to add. CMake verifies that the library exists before

# completing its build.
