Openssl error while compiling LibreOffice with Cygwin

I faced an error when I was compiling LibreOffice in cygwin env.
I installed openssl in cygwin evn, it cannot find openssl headers.

buckets\ssl_buckets.c(49): fatal error
C1083: Cannot open include file:
‘openssl /bio.h’: No such file or

I tried to download openssl source and build/install in cygwin it was pointless, this error still occurs.
I’d configured with Visual Studio 2017, 64bit
What do I have to do?
