# This script build the INDI library and drivers using the latest or a specific version.
# Before use, you must install the pre-requisites and configure a few options below.
# It install the drivers in /usr, this is intentional to not keep multiple version if some are already installed from packages.
# It is not intended for developper, beware it remove any local change in the source directory.
#
# See https://github.com/indilib/indi for the pre-requisites.
# Something like:
#   sudo apt-get install libnova-dev libcfitsio-dev libusb-1.0-0-dev zlib1g-dev libgsl-dev build-essential cmake git libjpeg-dev libcurl4-gnutls-dev libtiff-dev libfftw3-dev
# Some additional 3rdparty drivers may also need: 
#   sudo apt-get install libftdi-dev libgps-dev libraw-dev libdc1394-22-dev libgphoto2-dev libboost-dev libboost-regex-dev librtlsdr-dev liblimesuite-dev libftdi1-dev libavcodec-dev libavdevice-dev
#

# User Setup 
# you can change here how you want to build INDI 

# The INDI version to compile, use "latest" for the last release, "master" for the development code or any version tag like v1.8.7
# developer must specify "local" to use any local change, otherwise they are reverted before the compilation!
indiversion=latest
#indiversion=master
#indiversion=v1.8.7
#indiversion=local

# The list of additional library and drivers to install from indi-3rdparty
# The name to put here is the directory name from https://github.com/indilib/indi-3rdparty
# Be sure to list all the required library first
