Minor Description
Due to the way we choose to set the CRT linkage, this warning is displayed for every file. We should probably use the default flags, e.g. /MDd in debug, and stop linking the CRT statically, as it is not necessary, and proves to be error-prone.
Caveat: the CRT will need to be on the system on which Mesos is deployed; however, this is usually already the case due to VS redistributables. Nonetheless, I'd like to test on a "fresh" target system, e.g. Windows Server 1709, and if anything needs to be installed, document it.
