+./generate_cmake_lists.py --project-name <project-name> --arch <arch>
+
+- project-name - name of the new project
+- arch - arch type. make generates seperate CMakeLists files for
+ each architecture. To avoid collision in targets, only one of
+ them can be included in the super project.
+
+The primary objective of this file is to generate CMakeLists files
+for CLion setup.
+
+Steps to setup CLion.
+1) Open the generated CMakeList file in CLion as a project.
+2) Change the project root ANDROID_BUILD_TOP.
+(Also, exclude projects that you don't bother about. This will make
+the indexing faster).
