ImageGrid/ui (gen4)/Makefile

#**********************************************************************
#
# ImageGrid.Viewer Makefile...
#
#
# Make dependencies that need to be installed:
# 	- nodejs / npm 
# 		also nodejs-legacy seems to be required by some code...
# 	- npm i -g electron electron-rebuild asar less
# 	- wget
# 	- zip / unzip / zipnote
# 		if zipnote fails this is likely due to a bug in v3.0, to
# 		fix this by either upgrading to 3.1 or a patched version
# 		of 3.0...
# 		for more info and patch see: 
# 			https://goo.gl/csQmQo
# 	- Windows
# 		- MSVS -- to build node modules (sharp)
# 		- WiX
#	- Linux
#	- macOS
#	- iOS
# 	- Android
# 	- web
#
#
# Variables to control the build:
# 	APP_NAME	- Application name
# 	APP_BIN		- App binary name (ignored for MacOS)
#
# 	ARCH		- target achitecture (ia32, x86)
# 	TARGET_OS	- target OS (win32, linux, darwin)
# 	ELECTRON_DOWNOAD_URL
# 			- URL to download electron pinary
# 	BUILD_MODE	- can be "repack" or "in-place" (default)
#
# NOTE: when setting variables avoid using spaces and other characters 
# 	make can get fussy about...
# NOTE: to do a repack build call:
# 		(export BUILD_MODE=repack && make)
# NOTE: cross compilation is at this time not supported, if you try it 
# 	and it works then 1) you got very lucky and 2) tell me about it =)
# 	...at least the node native packages (sharp) will likely either 
# 	fail or	win get compiled to the wrong arch and not be used and
# 	for the most part ImageGrid is cleaver about and will simply not
# 	load the depending features...
#
#
#----------------------------------------------------------------------

# ToDo:
# 	- app icons...
# 	- might be a good idea to do a no-bin target -- exclude native...
# 	- add a cli-only build
# 	- installers:
# 		- msi
# 		- deb
# 		- ...
# 	- cross-compiling support...
# 	- upstream clean build: git clone -> make dist
# 	- nwjs???
