Hi, I had the same problem yesterday and found that this issuse is not closed.
I hope I can help you by sharing my solution.

The first thing to point out is that while libxslt and libxml2 can be easily installed in the msys2 environment, vs2022 is not well recognized even if you manually add their locations to the obj/Makefile.
However, installing libxslt and libxml2 in vs2022 is cumbersome and unnecessary.

So we can build the build toolchain we need directly in Mysys2 w64.

1. Install and libraries from MinGW: gcc make libxml2 libxslt.
   $ pacman -S mingw-w64-x86_64-gcc
$ pacman -S mingw-w64-x86_64-make
$ pacman -S mingw-w64-x86_64-libxml2
$ pacman -S mingw-w64-x86_64-libxslt

2. Modify the "nginx-x.x.x-RELEASE/auto/lib/libxslt/conf" file.
   -Because scripts in nginx cannot correctly validate libxml2 and libxslt in the msys2 w64 environment.
   -So delete everything related to validation and modify ngx_feature_path to the correct path.

   ngx_feature="libxslt"
   ngx_feature_name=
   ngx_feature_run=no
   ngx_feature_incs=""
   ngx_feature_path="/mingw64/include/libxml2"
   ngx_feature_libs="-lxml2 -lxslt"
   ngx_feature_test=""
   . auto/feature
   CORE_INCS="$CORE_INCS $ngx_feature_path"
   CORE_LIBS="$CORE_LIBS $ngx_feature_libs"
   NGX_LIB_LIBXSLT=$ngx_feature_libs
   ngx_feature="libexslt"
   ngx_feature_name=NGX_HAVE_EXSLT
   ngx_feature_run=no
   ngx_feature_incs="#include <libexslt/exslt.h>"
   ngx_feature_path="/mingw64/include/libxml2"
   ngx_feature_libs="-lexslt"
   ngx_feature_test="exsltRegisterAll();"
   . auto/feature
   CORE_LIBS="$CORE_LIBS -lexslt"
   NGX_LIB_LIBXSLT="$NGX_LIB_LIBXSLT -lexslt"

3. Then run ./configure.You can refer to the following.
   auto/configure \
--crossbuild=win32 \
--with-cc=gcc \
--without-http_rewrite_module \
--without-http_gzip_module \
--with-http_dav_module \
--add-module=./Lib/nginx-dav-ext-module-3.0.0

4. After successfully building the nginx executable, you need to copy the libxslt-1.dll and libxml2-2.dll to the same location as the nginx executable.They're usually in /mingw64/bin/.

Have a good day
