我需要在Windows UWP ARM64平台上使用boost。因此，我首先尝试使用32位ARM从源代码构建增强功能。这项工作不费吹灰之力，但是针对ARM64进行构建（我尝试使用V1.68，由于缺少库，因此无法使用较新的版本）会导致以下错误：
.../tools/build/src/tools\msvc.jam:1093: in set-setup-command

似乎在virtual-target.from-file ( file : file-loc : project )调用中需要设置file变量。
我查看了产生错误的文件，并试图找出变量应包含的内容。我没有找到设置变量的位置，但是在另一个平台（UWP ARM）上尝试显示该变量应该是
...\Microsoft Visual Studio\2017\Professional\VC\Auxiliary\Build\vcvarsx86_arm64.bat。这给了我一个问题，如果我通过在boost目录中调用以下命令正确地进行了设置：
./bootstrap.bat
./b2.exe architecture=arm windows-api=store toolset=msvc-14.1 address-model=64 --build-type=minimal --abbreviate-paths -j12 link=static threading=multi runtime-link=shared variant=debug --prefix=.../install/x64_uwp --with-system
然后我尝试在msvc.jam中手动设置此变量（请注意，有问题的设置可能会导致其他问题），但这只会导致以下几行的错误：
.../tools/build/src/kernel\modules.jam:107: in modules.call-in
*** argument error

* missing argument setup

.../tools/build/src/build\virtual-target.jam:142: in class@virtual-target.actualize
.../tools/build/src/tools\msvc.jam:1102: in set-setup-command
...
因此在设置阶段可能是一些问题。
有人在构建Boost（用于UWP ARM64）方面有经验，可以帮助我正确地设置和构建它吗？
