After updating from Protocol Buffers 2.5.0 to 2.6.0 compilation of the
generated source failed: "This file was generated by an older version of
protoc which is incompatible with your Protocol Buffer headers. Please
regenerate this file with a newer version of protoc.".
Turns out the source and headers generated by way of
FindProtobuf.cmake:PROTOBUF_GENERATE_CPP aren't updated. Adding a
dependency on the compiler executable fixes this issue.
When CMAKE_SYSTEM_NAME is 'WindowsCE':
* Set the Subsystem and EntryPointSymbol accordingly.
* When CMAKE_SYSTEM_VERSION is 8.0 (Windows CE 2013),
select the CE800 toolset by default.

Define the 'cmake -A' option to set CMAKE_GENERATOR_PLATFORM
without having to spell out the whole variable name. We choose
the name '-A' for "platform" because '-P' is already taken, and
in the common use case the "platform" is actually an architecture
(e.g. x64).
Teach the RunCMake test infrastructure to use -A to pass the generator
platform. Extend the RunCMake.GeneratorPlatform test with a case to
verify that the -A option cannot be repeated.
The CMAKE_SYSTEM_NAME is "CYGWIN", but we also define a variable
named "CYGWIN" to "1". Avoid allowing if() to expand the "CYGWIN"
string as a variable.
Legacy invocations may pass a variable name where "DEFAULT_MSG" belongs.
When comparing FPHSA_FAIL_MESSAGE to "DEFAULT_MSG", use a leading "x" on
both sides to avoid mistaking the value of the message for a variable
name.
Call SetSystemName, SetGeneratorPlatform, and SetGeneratorToolset
exactly once after reading CMakeSystem.cmake, and not again on another
call to enable_language() or project().
