Add project support Bazel build system.

[MiyamuraMiyako]

Is your feature request related to a problem?

I try build static library directly, but lib files can't use in my bazel project.
log cpr.lib(threadpool.obj) : error LNK2019: �޷��������ⲿ���� _Cnd_timedwait_for������ "public: __cdecl <lambda_eba37c162f1e7731b0928a0b0fca0ed0>::operator()(void)const " (??R<lambda_eba37c162f1e7731b0928a0b0fca0ed0>@@QEBA@XZ) �������˸÷��� cpr.lib(async.obj) : error LNK2019: �޷��������ⲿ���� __std_init_once_link_alternate_names_and_abort������ "public: __cdecl std::_Init_once_completer::~_Init_once_completer(void)" (??1_Init_once_completer@std@@QEAA@XZ) �������˸÷���
I can't find the reason yet.
this is my BUILD.bazel file's some content:

cc_import(
    name = "zlibstatic",
    hdrs = [],
    static_library = "libs/win-x64/zlibstatic.lib",
    visibility = ["//visibility:public"],
)

cc_import(
    name = "curl",
    hdrs = [],
    deps=[":zlibstatic"],
    static_library = "libs/win-x64/libcurl.lib",
    visibility = ["//visibility:public"],
)

cc_import(
    name = "cpr",
    hdrs = glob([
        "src/cpr/*.h",
    ]),
    static_library = "libs/win-x64/cpr.lib",
    deps=[":zlibstatic",":curl"],
    visibility = ["//visibility:public"],
)

cc_binary(
    name = "..........",
    srcs = glob([
        "**/*.cpp",
        "**/*.hpp",
        "**/*.h",
    ]),
    copts = [
        "/utf-8",
        "-std:c++17",
        "-Bv",
        "-W3",
        "-MT",
        "-D_UNICODE",
        "-DUNICODE",
    ],
    includes = ["src"],
    linkopts = [
        "-ENTRY:wWinMainCRTStartup",
        "-SUBSYSTEM:WINDOWS",
        "-NODEFAULTLIB:libcmt.lib",
    ],
    linkstatic = 1,
    deps = [
        ..........
        ":zlibstatic",
        ":curl",
        ":cpr",
        .........
    ],
)

Possible Solution

If cpr support bazel directly, maybe it will be easier to use. But I can't successfully convert the cmake project to a bazel project yet.

Sadly I never directly worked with base yet.
Bat some time ago, someone else put in the work to write some bazel rules here: https://github.com/hedronvision/bazel-make-cc-https-easy

I would love to merge a PR adding bazel support if someone is volunteering to maintain it.

Okay, I'm also working on how to do this.
