Can't seem to get Windows x86 binaries to build

Question

Hello! As the title says, I can't seem to get LWJGL to build for x86 Windows with x64 toolchain.
My steps:

set PATH_OLD=%PATH%
set LWJGL_BUILD_ARCH=x86
set LWJGL_BUILD_OFFLINE=true
set JAVA_HOME=F:\.jdks\jdk-17.0.2 // 64 bit
set PATH=F:\.jdks\jdk-17.0.2\bin;%PATH_OLD%
set VSCMD_SKIP_SENDTELEMETRY=true
vcvarsall x86

set JAVA_HOME=F:\.jdks\jdk-17.0.2-x86 // 32 bit
set PATH=F:\.jdks\jdk-17.0.2-x86\bin;%PATH_OLD%
ant compile-native

Problem: libffi does not seem to get picked up for some reason:

Hey @xxDark,

Have you made sure that PATH_OLD does not already contain a JDK? Also:

1. Try setting up JAVA_HOME only, without changing PATH. The ant script will pick it up automatically. It's cleaner that way and you can change JDK versions at will.
2. You may use vcvarsall amd64_x86, which sets up a 64-bit compiler that produces x86 code. It's more efficient.
