title: use cython and clang to compile excutable file
body: <p>I am trying to convert my python project with cython to c source and compile it with clang,I compile it in a windows vitural machine with python3.8.
  this is my compile options:</p>
  <pre><code>./clang -std=c11  test.c -I&quot;D:\env\python38\include&quot; -L&quot;D:\env\python38\libs&quot; -lpython38 -o test.exe -DMS_WIN64 -municode 
  </code></pre>
  <p>It works very well.
  But when I move test.exe to another windows without python env and run test.exe, it reminds me cant't find python38.dll. Actually when I provide python38.dll in the same dir,it gives the error:</p>
  <pre><code>Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding
  Python runtime state: core initialized
  ModuleNotFoundError: No module named 'encodings'
  
  Current thread 0x00001bd8 (most recent call first):
  &lt;no Python frame&gt;
  </code></pre>
  <p>I wonder to know if using cython c source to compile exe have to require python installation to execute. Is there any way to compile it without the need of python env at runtime?</p>
