当我尝试使用 Cyginx 在我的 Windows Server 2019 系统上从源代码构建 Ejabbed 时出现此错误
$ make install
C:\cygwin64\home\erl10.2\erts-10.2\bin\escript.exe rebar configure-deps
==> lager (configure-deps)
==> p1_utils (configure-deps)
==> cache_tab (configure-deps)
==> fast_tls (configure-deps)
checking for gcc... **cl.exe**
checking whether the C compiler works... no
configure: error: in `/home/Administrator/ejabberd/deps/fast_tls':
configure: error: C compiler cannot create executables
See `config.log' for more details
ERROR: Command ['configure-deps'] failed!
make: *** [Makefile:111: deps/.built] Error 1
然后我发现它与 GCC 或环境变量有关，所以我尝试一个一个地安装依赖项，然后我尝试再次制作......它工作正常，直到这个

我知道它应该是 GCC 而不是 cl.exe ，他们从哪里获得 GCC 安装路径或者它是如何变成 cl.exe 的？
