#!/bin/sh

# This script runs building project using CMakeLists.txt from current folder.
# The result of building places into BUILD_DIR directory.
# Usage: 
#     build.sh [<configuration>] [<platform>] [rebuild|clean] [no-tls] [static]
# Where
#     <configuration> - Debug or Release
#     <platform>      - x86 or x64
#     clean           - removes build directory
#     rebuild         - performs clean and build
#     no-tls          - build without TLS support
#     static          - build the framework as a static library, static samples and tests (without TLS support)
# The default configuration is 'Release x64'.
#
# WARNING: you can set the next environment variables
#     APP_VERSION - the version of target in format major[.minor[.patch]], i.e. 1.2.6
#                   If you want to specify version you must set 'set APP_VERSION=...'
#                   in your caller script or command line. Otherwise the default version 
#                   from sources will be used.
