Summary0015867: Meta-projects generated for Visual Studio 2013 solutions are always multi-byte
DescriptionExpected Behavior:
If "add_definitions(-D_UNICODE -DUNICODE)" was added to the CMakeList.txt, all project files for Visual Studio solutions should be marked as unicode.

Real Behavior:
While the behavior is as expected in Visual Studio 2008, at least Visual Studio 2013 does not show the expected behavior and sets meta projects (e.g. ZERO_CHECK) to multi-byte.

Problem:
Starting with Visual Studio 2013, MFC with multi-byte character set is marked deprecated and no longer possible without installing additional software.
Steps To Reproduce* Create a simple CMake project
* Add "add_definitions(-D_UNICODE -DUNICODE)" to the CMakeList.txt
* Generate a Visual Studio 2013 solution
* Open the generate solution with Visual Studio
* Verify the character set of meta projects (e.g. ZERO_CHECK)

 What is the problem? Are you getting a warning, error, unable to compile, or something else?

https://cmake.org/gitweb?p=cmake.git;a=blob;f=Source/cmVisualStudio10TargetGenerator.cxx;h=6e1fb5 [^]

From cmVisualStudio10TargetGenerator.cxx line 751 to 768, it appears CharacterSet will always be set to MultiByte for a UTILITY target. It seems that logic needs changed.

 With a plain Visual Studio 2013 installation I get the following error for all meta projects (if MFC is used and enabled in the project):

Error 1 error MSB8031: Use of MBCS encoding in MFC projects require an additional library to be downloaded and installed. Please see http://go.microsoft.com/fwlink/?LinkId=286820 [^] for more information. C:\Program Files\MSBuild\Microsoft.Cpp\v4.0\v120\Microsoft.CppBuild.targets

This forces me to either
* manually switch all meta projects from multi-byte to unicode (and do this every time when CMake detected changes)
* install the additional library although i do not use MFC with multi-byte characters (of course this is possible, but unnecessary; also this feature might be completely removed in future VS version)

The same problem is described here:

 Ok. So does that mean your simple cmake project is setting CMAKE_MFC_FLAG?

 Yes, I have "set(CMAKE_MFC_FLAG 2)" in my root CMakeList.txt file.
Sorry for not-mentioning this in my "Steps To Reproduce".
