* build OpenSSL using MSVC toolchain on Windows
* Display lib name in progress message
Before this commit, when building OpenSSL using MSVC, the progress
message would display "Building openssl_msvc_".
After this commit, the progess message would display
"Building openssl".
* Add test to verify linkage with OpenSSL libs
* Add test to verify linkage with Curl libs
Note that linker errors occur in applications that link with libssl
and libcrypto if libcrypto comes before libssl on the linker
command-line. Swapping the order of libcrypto and libssl in
BUILD.openssl.bazel resolved the issue.
* Added `targets` API to all existing build rules
* Updated examples
* Restore making the make toolchain always available.
* Add support for generator cmake parsing and setting CMAKE_MAKE_PROGRAM
* Cleaned up duplicate generator arguments
* Fixed cmake tests
* Updated docs
* Addressed PR feedback
* Fixed missing and incorrect generators
* Fixed `generate_args` name
