Well... how's that possible that just adding a small property has caused build break on Windows?

@justinjoy : have you checked how it works in both modes - with haicrypt+srt in one library file and in two separate files?

I missed the separating option. For both cases, they work in linux environment.
However, in CI, it seems to use a different version of OpenSSL because I can see the below log in the middle of CI report.

C:\projects\srt\haicrypt\hc_openssl_aes.c(267): warning C4013: 'AES_ctr128_encrypt' undefined; assuming extern returning int [C:\projects\srt\srt.vcxproj]

The function, AES_ctr128_encrypt, has disappeared in OpenSSL-1.1, but I'm not sure.

Hello @justinjoy , could you please try updating your branch with the latest to see if CI passes this time? Thank you!
