"Unresolved external symbols" when compiling on Windows

[andrejp88]

• OS: Windows

Bug: When dub gets to the linking step, the following errors occur:

scone.lib(windows_3c8_38d.obj) : error LNK2019: unresolved external symbol GetSystemMetrics referenced in function _D5scone2os7windows9WindowsOS6resizeFxkxkZv
scone.lib(windows_3c8_38d.obj) : error LNK2019: unresolved external symbol SetWindowPos referenced in function _D5scone2os7windows9WindowsOS10repositionFNbNiiiZv
.dub\build\application-debug-windows-x86_64-dmd_2088-F83972565FA2F7DB289FECBA209E86F8\openmc173.exe : fatal error LNK1120: 2 unresolved externals
Error: linker exited with status 1120
dmd failed with exit code 1.

tl;dr It fails to locate "GetSystemMetrics" and "SetWindowPos".

Reproduce: I added scone 2.1.2 to my dependencies, copied in the example code from the readme, and compiled using the following command:
dub run --compiler=dmd -a=x86_64 -b=debug -c=application'

Additional context: I fixed this by going into scone/os/windows.d and adding the following line:
pragma(lib, "User32.lib");
Which was suggested in this thread on the D forums.

I'd make a pull request, but I don't know if this is the "right" way to fix this error, and it may not even be scone's fault, since it isn't the one who declares those external symbols.

I cannot reproduce this on my PC, but I got an email today about this exact issue.

Looking into it.

Also, that is me and Dennis in that thread ;)

I think I've solved it, but unsure why this bug started to happen. Going to do some more testing.

If the problem still persists, please reopen this issue 👍
