+# - Find the Windows SDK aka Platform SDK
+# taken from https://github.com/ampl/mp/blob/master/support/cmake/FindWindowsSDK.cmake
+#
+# Relevant Wikipedia article: http://en.wikipedia.org/wiki/Microsoft_Windows_SDK
+#
+# Pass "COMPONENTS tools" to ignore Visual Studio version checks: in case
+# you just want the tool binaries to run, rather than the libraries and headers
+# for compiling.
+#
+# Variables:
+# WINDOWSSDK_FOUND - if any version of the windows or platform SDK was found that is usable with the current version of visual studio
+# WINDOWSSDK_LATEST_DIR
+# WINDOWSSDK_LATEST_NAME
+# WINDOWSSDK_FOUND_PREFERENCE - if we found an entry indicating a "preferred" SDK listed for this visual studio version
+# WINDOWSSDK_PREFERRED_DIR
+# WINDOWSSDK_PREFERRED_NAME
+#
+# WINDOWSSDK_DIRS - contains no duplicates, ordered most recent first.
+# WINDOWSSDK_PREFERRED_FIRST_DIRS - contains no duplicates, ordered with preferred first, followed by the rest in descending recency
+#
+# Functions:
+# GetUMWindowsSDKLibraryDir(<output variable>) - Find the latest SDK user mode (um) library directory,
+# architecture dependent
+# GetUMWindowsSDKIncludeDir(<output variable>) - Find the latest SDK user mode (um) include directory
+#
+# windowssdk_name_lookup(<directory> <output variable>) - Find the name corresponding with the SDK directory you pass in, or
+# NOTFOUND if not recognized. Your directory must be one of WINDOWSSDK_DIRS for this to work.
+#
+# windowssdk_build_lookup(<directory> <output variable>) - Find the build version number corresponding with the SDK directory you pass in, or
+# NOTFOUND if not recognized. Your directory must be one of WINDOWSSDK_DIRS for this to work.
+#
+# get_windowssdk_from_component(<file or dir> <output variable>) - Given a library or include dir,
+# find the Windows SDK root dir corresponding to it, or NOTFOUND if unrecognized.
+#
+# get_windowssdk_library_dirs(<directory> <output variable>) - Find the architecture-appropriate
+# library directories corresponding to the SDK directory you pass in (or NOTFOUND if none)
+#
+# get_windowssdk_library_dirs_multiple(<output variable> <directory> ...) - Find the architecture-appropriate
+# library directories corresponding to the SDK directories you pass in, in order, skipping those not found. NOTFOUND if none at all.
+# Good for passing WINDOWSSDK_DIRS or WINDOWSSDK_DIRS to if you really just want a file and don't care where from.
+#
+# get_windowssdk_include_dirs(<directory> <output variable>) - Find the
+# include directories corresponding to the SDK directory you pass in (or NOTFOUND if none)
+#
+# get_windowssdk_include_dirs_multiple(<output variable> <directory> ...) - Find the
+# include directories corresponding to the SDK directories you pass in, in order, skipping those not found. NOTFOUND if none at all.
+# Good for passing WINDOWSSDK_DIRS or WINDOWSSDK_DIRS to if you really just want a file and don't care where from.
