By default Visual Studio projects do not compile source files in parallel. Add "/MP" flag to enable that. From scratch OCIO build on Ryzen 5950X, VS2022: 580sec -> 208sec. Most of remaining single-threaded time is cloning external libraries or building external libraries (most of them don't do parallel compilation either). But within building OCIO itself, CPU usage goes close to 100% instead of 5%. Signed-off-by: Aras Pranckevicius <aras@nesnausk.org>
