Import errors when running `swift build`

I'm following the directions in the README, but when I get to swift build I see a number of import errors:

Is there perhaps another way to build this project using cmake?

I'm having the same issues, on windows 10, both with Swift 5.8 and Swift 5.9 Development (got it from the official downloads)

@shepting
I was able to get rid of this errors. There are some symbolic links in this repository. According to this answer on StackOverflow https://stackoverflow.com/questions/5917249/git-symbolic-links-in-windows/59761201#59761201 It is necessary to turn a git configuration on.

However now I have another missing file

indexstore-db\lib\Support\Logging.cpp:19:10: fatal error: 'dispatch/dispatch.h' file not found
#include <dispatch/dispatch.h>
         ^~~~~~~~~~~~~~~~~~~~~

And this I don't know where it is supposed to come from :/

If you look at our instructions for building on Linux you'll see we're passing some extra -I options to find toolchain headers; does something similar work on Windows?

[compnerd]

@benlangmuir yes, that would work on Windows as well. -Xcc -I${env:SDKROOT}\usr\include or -Xcc %SDKROOT%\usr\include (depending on the shell) should work I believe.
