CMake: How to avoid link error when the project contains .asm MASM sources with VS2013?

I'm using CMake 3.0.1 with "Visual Studio 12 2013" generator.

I added .asm files to a project. Then, the linker error LNK2026 has occurred when cmake --build ..

The LNK2026 error is module unsafe for SAFESEH image. http://msdn.microsoft.com/en-us/library/100ezk17.aspx

If I add a project property manually as following, it works fine.

<UseSafeExceptionHandlers>true</UseSafeExceptionHandlers>

Could I avoid the linker error without changing the generated project file?

Here is a simple project that cannot build with generated .vcxproj.

a.c

extern void ExAsmCode();

int main(int argc, char** argv)
{
    ExAsmCode();
    return 0;
}

m.asm

.586
.model flat, c
MessageBoxA     proto STDCALL :dword, :dword, :dword, :dword

.data

MSG          DB 'masm', 0

.code

ExAsmCode PROC
    invoke MessageBoxA, 0, offset MSG, offset MSG, 0
    ret
ExAsmCode ENDP

end

CMakeLists.txt

CMAKE_MINIMUM_REQUIRED(VERSION 3.0)

PROJECT(Ex)

ENABLE_LANGUAGE(ASM_MASM)

add_executable(Ex a.c m.asm)

Add /safeseh flag to source:

set_source_files_properties(
    my.asm
    PROPERTIES
    COMPILE_FLAGS "/safeseh"
)
