cmake_build.sh

#!/bin/bash

# Build and test the cmake build
# Should work out of the box on Linux and macOS
# Windows requires a bash shell, e.g. Git Bash
# conan requires that conan is installed
#
# Before:
# rm -rf build && cd build
#
# Then:
# bash ../cmake_build.sh <lib-source> <build-type> <Release|Debug>
#
#
# Usage examples:
#
# Retrieve all dependencies from conan and build a static library in Release mode
# bash ../cmake_build.sh conan static Release
#
# Use conan w/ pkg-config to find dependencies and build a static library in Debug mode
# (this is mostly for testing pkg-config support and is not supported on Windows)
# bash ../cmake_build.sh pkg static Debug
#
# Use system-installed libraries available to CMake and build a shared library in Release mode
# bash ../cmake_build.sh system shared Release
#
#
# Exports a CMake config file to ${CMAKE_INSTALL_PREFIX} (or ${HOME}/tmp/im by default)
# and builds a small test program using the exported config file and the ImageMagick library
