This cmake file directly sets CMAKE_<LANG>_FLAGS, which doesn't
show up in the COMPILE_COMMANDS target property and so our
dolphin_disable_warnings_msvc macro failes to remove it.
So we will just commit it out.
On a few of our buildbot instances, we get warnings about the usage of
deprecated functions. We should correct these, especially if we're
delegating to system versions of the libraries if they're available.
However, in order to do that, we need to update our library variant from
2.1.1 so that the non-deprecated alternatives are actually available.
PolarSSL has been renamed to "mbed TLS" and version 2.0 dropped backwards
compatibility. This commit adds only the necessary files without any
modifications, so it doesn't compile yet.
