# This Makefile can be used on both unix-like (use make) & windows (with GNU make)
#
# append the Configuration variable to 'make' call with value to use in '/p:Configuration='
# of msbuild command.
#
# Example:
#    make Configuration=Release
#
#
# Some targets:
#  - all: everything (including APK)
#  - native: build the native libs
#  - java: build the java libs
#  - nuget: restore NuGet packages
#  - msbuild: build the project
#  - apk: same as all
#
#  - distclean: run a 'git clean -xdff'. Remove everyhing that is not in the git tree.
#  - clean: all clean_* targets below
#  - clean_native: clean native lib
#  - clean_java: call clean target of java libs
#  - msbuild_clean: call clean target of java libs
