example_build_script_2

#!/bin/bash
#
# Another example script for building dependencies and xReg.
# Compared to the other bash build script (example_build_script) which only uses
# static libraries and links from each dependency's cmake build directory, this script
# allows for shared libraries and will also install all dependencies into a specified
# install prefix. This allows users to pull in all dependencies by just setting the
# CMAKE_PREFIX_PATH to this directory when configuring the xReg build.

# stop after the first failed command
set -e

# Disable these to skip downloading and building dependencies
: ${NEED_TO_DOWNLOAD_THIRD_PARTY:=true}
: ${NEED_TO_BUILD_THIRD_PARTY:=true}

# Set this to false to not build xreg and only build the dependencies
: ${NEED_TO_BUILD_XREG:=true}

# This can be set to false when building on servers which do not have appropriate UI
# dependencies. This can avoid linker errors.
: ${XREG_DO_GUI:=true}

# Use these to explicitly set the build config
#BUILD_CONFIG="Debug"
#BUILD_CONFIG="Release"

# This uses a default config of release, but is overriden by the BUILD_CONFIG
# environment variable
: ${BUILD_CONFIG:=Release}

# Use these to explicitly set buiding shared or static libs
#BUILD_SHARED="ON"
#BUILD_SHARED="OFF"

# This defaults to static libs, but is overriden by the BUILD_SHARED environment variable
: ${BUILD_SHARED:=OFF}

# directory of the xReg repo (since this script is located in the repo root)
XREG_DIR="$(cd "$(dirname "$0")"; pwd)"

# use this to build the xreg library and apps within the repo directory:
XREG_BUILD_DIR="$XREG_DIR/build"
# use this to build the xreg library and apps in a tmp directory:
#XREG_BUILD_DIR="$HOME/tmp/xreg_build"

# set as blank to not install xreg, otherwise set to installation prefix
# The value here is the default value and is overriden by a XREG_INSTALL_DIR environment variable
: ${XREG_INSTALL_DIR:="$HOME/xreg"}

# Set DEPS_DIR to a directory outside of the xReg repo in which to download and build dependencies
