|
+// HOW TO USE THIS CODE
|
|
|
+//
|
|
|
+// The purpose of this file is to find the folders that contain libraries
|
|
|
+// you may need to link against, on Windows, if you are linking with any
|
|
|
+// compiled C or C++ code. This will be necessary for many non-C++ programming
|
|
|
+// language environments that want to provide compatibility.
|
|
|
+//
|
|
|
+// We find the place where the Visual Studio libraries live (for example,
|
|
|
+// libvcruntime.lib), where the linker and compiler executables live
|
|
|
+// (for example, link.exe), and where the Windows SDK libraries reside
|
|
|
+// (kernel32.lib, libucrt.lib).
|
|
|
+//
|
|
|
+// We all wish you didn't have to worry about so many weird dependencies,
|
|
|
+// but we don't really have a choice about this, sadly.
|
|
|
+//
|
|
|
+// I don't claim that this is the absolute best way to solve this problem,
|
|
|
+// and so far we punt on things (if you have multiple versions of Visual Studio
|
|
|
+// installed, we return the first one, rather than the newest). But it
|
|
|
+// will solve the basic problem for you as simply as I know how to do it,
|
|
|
+// and because there isn't too much code here, it's easy to modify and expand.

+// You might think that's way too much code to do something as simple
|
|
|
+// as finding a few library and executable paths. I agree. However,
|
|
|
+// Microsoft's own solution to this problem, called "vswhere", is a
|
|
|
+// mere EIGHT THOUSAND LINE PROGRAM, spread across 70 files,
|
|
|
+// that they posted to github *unironically*.
|
|
|
+//
|
|
|
+// I am not making this up: https://github.com/Microsoft/vswhere
|
|
|
+//
|
|
|
+// Several people have therefore found the need to solve this problem
|
|
|
+// themselves. We referred to some of these other solutions when
|
|
|
+// figuring out what to do, most prominently ziglang's version,
|
|
|
+// by Ryan Saunderson.
|
|
|
+//
|
|
|
+// I hate this kind of code. The fact that we have to do this at all
|
|
|
+// is stupid, and the actual maneuvers we need to go through
|
|
|
+// are just painful. If programming were like this all the time,
|
|
|
+// I would quit.
|
|
|
+//
|
|
|
+// Because this is such an absurd waste of time, I felt it would be
|
|
|
+// useful to package the code in an easily-reusable way, in the
|
|
|
+// style of the stb libraries. We haven't gone as all-out as some
|
|
|
+// of the stb libraries do (which compile in C with no includes, often).
|
|
|
+// For this version you need C++ and the headers at the top of the file.
|
|
|
+//
|
|
|
+// We return the strings as Windows wide character strings. Aesthetically
|
|
|
+// I don't like that (I think most sane programs are UTF-8 internally),
|
|
|
+// but apparently, not all valid Windows file paths can even be converted
|
|
|
+// correctly to UTF-8. So have fun with that. It felt safest and simplest
|
|
|
+// to stay with wchar_t since all of this code is fully ensconced in
|
|
|
+// Windows crazy-land.
|
|
|
+//
|
|
|
+// One other shortcut I took is that this is hardcoded to return the
|
|
|
+// folders for x64 libraries. If you want x86 or arm, you can make
|
|
|
+// slight edits to the code below, or, if enough people want this,
|
|
|
+// I can work it in here.
