How to bundle OpenSSL v3 binaries with application on Windows?

Withing executable I have libcrypto-3-x64.dll and libssl-3-x64.dll.

In ./lib directory I have DLLs in engines-3 and ossl-modules.

Good, but to start application I forced to use *.bat file with something like:

set OPENSSL_MODULES=./lib/ossl-modules
set OPENSSL_ENGINES=./lib/engines-3
start "" my_app.exe %

How to avoid using of this *.bat file, and have only my_app.exe that won't produce Windows error message?

Want to add that:

int main( int argc, char ** argv )
{
	qputenv( "OPENSSL_MODULES", "./lib/ossl-modules" );
	qputenv( "OPENSSL_ENGINES", "./lib/engines-3" );

doesn't solve the problem.

And a following *.manifest:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
    <security>
      <requestedPrivileges>
        <requestedExecutionLevel level="asInvoker" uiAccess="false"></requestedExecutionLevel>
      </requestedPrivileges>
    </security>
  </trustInfo>
  <application xmlns="urn:schemas-microsoft-com:asm.v3">
    <windowsSettings>
	  <environment name="OPENSSL_MODULES" value="./lib/ossl-modules" />
	  <environment name="OPENSSL_ENGINES" value="./lib/engines-3" />
	</windowsSettings>
  </application>
</assembly>

doesn't solve the problem too.

Thanks.
