Message : Build: Embed version/API/(C) info in MSVC DLLs Based on: https://github.com/TheDorkKnight/libjpeg-turbo/commit/da7a18801a5c305d3f8a71b065f179f1e22b73ae Closes #576

# Anything that must be linked against the shared C library on Windows must
# be built in this subdirectory, because CMake doesn't allow us to override
# the compiler flags for each build type except at directory scope.  Note
# to CMake developers:  Add a COMPILE_FLAGS_<CONFIG> target property, or
# better yet, provide a friendly way of configuring a Windows target to use the
# static C library.
