[CMake] PreprocessToFile

[KK]

Oh, maybe you misunderstood me. I know, that CMake does no 
preprocessing. This is done by the preprocessor.

But, what I want, is that the generated solution/VS-project with CMake 
gives me the result like in the part I've pasted below. This should be 
part of the generated files. And my question is, is it possible to 
generate this and if, how?

=====
<ClCompile Include="abc.cpp">

<PreprocessToFile Condition="'$(Configuration)|(Platform)'=='Release|x64'">

false

</PreprocessToFile>

<PreprocessKeepComments 
Condition="'$(Configuration)|$(Platform)'=='Release|x64'">

false

<PreprocessKeepComments>

</ClCompile>
