REM This Windows batch file builds this repository for the following targets:
REM 64/32-bit Release/Debug
REM It uses CMake to genererate the project files and then invokes msbuild
REM to build them.
REM The update_external_sources.bat batch file must be executed before running
REM this batch file
REM
REM Arguments:
REM None: Runs CMake and builds all 4 combinations
REM Argument contains:
REM     cmake (case insensitive): Deletes build and build32 and runs just CMake on both
REM     32: Deletes build32, runs CMake and builds 32-bit versions
REM     64: Deletes build, runs CMake and builds 64-bit versions
REM Example:
REM build_windows_targets.bat 64
REM deletes build, creates build, runs CMake and compiles 64-bit Debug and Release.
