Zephir during compile make errors

[dox07]

Environment: OS: Win 10, php 7.4.x.

I have installed Zephir(0.17.0), zephir_parser(1.6.0) - OK.
Command zephir init - OK, then i created tsheet.zep file with source code.

But when i am trying compile my zephir class i get error. My compile command is: php zephir.phar compile

i got following:

 Preparing for PHP compilation...
 Preparing configuration file...
 ERROR: mc is required
 Compiling...

My question is: What means: "mc is required" ? What should i do for resolving this error ?

Error is resolved after properly installed php_sdk, appropriated visual studio. And i should building dll extension in x64 command prompt.
