build fails on windows

[parthibx24]

When building in a windows environment I encountered the following issues.

1. cant find ssl and crypto libraries

   Compiling tquic v0.2.0 (E:\Docs\devw\2023\tquic)
error: could not find native static library `ssl`, perhaps an -L flag is missing?

error: could not compile `tquic` (lib) due to previous error

Looks like the libraries are stored under the out/build/Debug folder not out/build. Can be fixed by adding this folder in build.rs.

    Directory: E:\Docs\devw\2023\tquic\target\debug\build\tquic-959af7c8517dba55\out\build\Debug


Mode                 LastWriteTime         Length Name
----                 -------------         ------ ----
-a----        11/20/2023  10:31 PM        5014178 crypto.lib
-a----        11/20/2023  10:33 PM        1619950 ssl.lib

2. tikv-jemallocator wont compile

[ERROR rust_analyzer::main_loop] FetchBuildDataError:
The following warnings were emitted during compilation:

note: To improve backtraces for build dependencies, set the CARGO_PROFILE_DEV_BUILD_OVERRIDE_DEBUG=true environment variable to enable debug information generation.

as a workaround this library can be disabled for windows

@parthibx24 Thank you for your detailed feedback and suggestions!

As outlined in the project documentation , TQUIC does not currently support Windows OS.

However, We plan to extend its support to Windows in later versions.
