Cannot build with `error[E0308]: mismatched types` in azul-text-layout using x86_64-pc-windows-msvc toolchain

[usagi]

Description

Some part of Azul's build system is broken maybe. I tried build Azul with a minimal bin-crate but I got these 9 errors in belows:

Pattern 1: expected i32, found i64 ( x3 errors )

C:\Users\usagi\.cargo\git\checkouts\azul-f3b1e21a5e685cad\17b76b0\cargo\azul-text-layout\../../azul-text-layout\text_shaping.rs:309:73

help: you can convert an `i64` to `i32` and panic if the converted value wouldn't fit

Version / OS

• azul version: 17b76b0 ( azul = { git = "https://github.com/maps4print/azul" } )
• Operating system: Microsoft Windows 10 ( 64-bit ) 10.0.19041.113

1. cargo new a
2. cd a
3. Append line azul = { git = "https://github.com/maps4print/azul" } in the [dependencies] section in the Cargo.toml.
4. cargo build

Additional Information

I think, it is very similar problem in these:

1. #203 (comment)
2. #163 (comment)

But #203 and #163 is the Harfbuzz issue and it's cleared at least the main problems. And, I tried add the msvc's cmake.exe path to PATH environment, and checked using where.exe, and removed the other CMake installs but the problem is not solved. 😢

Additional researchAdditional informations:

• I checked built freetype.lib's memory model: dumpbin /headers freetype.lib in the target directory -> 8664 machine (x64); The building of the native library level has no problems.

I found the factor. I'll PR in near future about the issue. I think, the factor is complexed windows and msvc's memory layout model (LLP64) but the solution is a little fixing for azul. Wait a moment please. 👍
