## GNU Makefile designed to build a static library which can be shared across multiple architectures.

## Input environment:
|

|
|
# CC - compiler (gcc or clang)
|
||
|
|
# AR - archiver (ar)
|
||
|
|
# JNI_PLATFORM - "linux" for linux and "darwin" for mac.
|
||
|
|
# LIB_DIR - where the static library will be built in
|
||
|
|
# OBJ_DIR - where the obj files will be built in (defaults to LIB_DIR)
|
||
|
|
# LIB_NAME - the name of the native library
|
