This crate contains the logic to build OpenSSL and is intended to be consumed by the openssl-sys crate. You likely in theory aren't interacting with this too much!

Building OpenSSL for windows-msvc targets, users can choose whether to enable assembly language routines, which requires nasm.
The build process will automatically detect whether nasm.exe is installed in PATH. If found, the assembly language routines will be enabled (in other words, the no-asm option will NOT be configured).
You can manipulate this behavior by setting the OPENSSL_RUST_USE_NASM environment variable:

• 1: Force enable the assembly language routines. (panic if nasm.exe is not availible.)
• 0: Force disable the assembly language routines even if the nasm.exe can be found in PATH.
• not set: Let the build process automatically detect whether nasm.exe is installed. If found, enable. If not, disable. However, this environment variable does not take effects on non-windows platforms.
