PHP 7.4.2 [extension] build errors on Windows

I am using a package(SAP RFC Connector) for some time now that is retrieved from here https://github.com/gkralik/php7-sapnwrfc

The package is working as expected on all PHP versions until 7.4.2 with source build.

I've built the php_sapnwrfc.dll from source with both VS2015 and VS2019 but I am unable to get it working due to these errors, that I am unable to solve.

For building, I've used this procedure:

1. https://gkralik.github.io/php7-sapnwrfc/building.html#building-on-windows
2. https://wiki.php.net/internals/windows/stepbystepbuild_sdk_2

Is there someone out there that knows how to solve this?

With VS2019 I got this error but no one knows what it means, especially the warning with the core number.

Warning: PHP Startup:
Can't load module 'C:/ownprograms/wamp/bin/php/php7.4.2/ext/php_sapnwrfc.dll' as it's linked with 14.24, but the core is linked with 14.16 in Unknown on line 0

With VS2015 I got this error but this is due to compiler.

[17-Feb-2020 10:48:43 UTC] PHP Warning:  PHP Startup: sapnwrfc: Unable to initialize module
Module compiled with build ID=API20190902,TS,VS16
PHP    compiled with build ID=API20190902,TS,VC15
These options need to match

PHP version: 7.4.2 TS

Any help would be appreciated.
