hasn't been implemented yet, to unblock building master.

Adding CMake module to enable/disable transport adapters
TRANSPORT ADAPTER BUILD
Default: If no option is explicitly added, curl will be used for POSIX and WIN HTTP for WIndows
Windows: Both CURL and WIN_HTTP can be build to be used.
POSIX: Only CURL is acceptable. If WIN_HTTP is set, generate step will fail for user
Defines `BUILD_WIN_HTTP_TRANSPORT_ADAPTER` and `BUILD_CURL_HTTP_TRANSPORT_ADAPTER` for source code
