Define allowed includes in msbuild - msbuild

Question

I am trying to build a project in ANSI-C on Microsoft Windows [Version 10.0.14393] with msbuild version Microsoft (R)-Buildmodul, Version 15.1.1012.6693
I get to compile everything correct, with the setup shown below.
Project Strcuture
The projectfolder is structed like this:
- projectfolder
- a.vcxproj
- main.c
- main.h
- other.c
- other.h
- test.c
- test.h
main.c
#include <stdio.h>
#include "main.h"
#include "test.h"
int main() {
printf("Hello World\n");
test_printf();
return 0;
}
main.h
#ifndef MAIN_H_
#define MAIN_H_
#endif // !MAIN_H_
other.c
#include "other.h"
#ifdef dummy
int some_number = 3;
#endif // dummy
other.h
#ifndef OTHER_H_
#define OTHER_H_
#define dummy
#ifdef dummy
extern int some_number;
#endif // dummy
#endif // OTHER_H_
test.c
#include <stdio.h>
#include "test.h"
extern int test_printf(void) {
printf("Hello from test.c");
return 0;
}
test.h
#ifndef TEST_H_
#define TEST_H_
extern int test_printf(void);
#endif // !TEST_H_
The build script a.vcxproj looks like this (Generated by Visual Studio 2017 Community and then adapted to my needs in an editor):

** This compiles fine without warnings/rrors to a *.exe **
What I Want To Achieve
But I want to spefcify for each object file that gets generated (main.obj, other.obj and test.obj) the sources the compiler is allowed to use fot the compile step.
If I change the <ItemGroup> of each to this (every to be generated *.obj files, gets the *.c files it should use for the compile step:
<ItemGroup>
<ClCompile Include="other.c"> <!-- !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! -->
<DisableLanguageExtensions Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">true</DisableLanguageExtensions>
<CompileAs Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">CompileAsC</CompileAs>
</ClCompile>
</ItemGroup>
<ItemGroup>
<ClCompile Include="test.c;other.c"> <!-- !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! -->
<DisableLanguageExtensions Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">true</DisableLanguageExtensions>
<CompileAs Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">CompileAsC</CompileAs>
</ClCompile>
</ItemGroup>
<ItemGroup>
<ClCompile Include="main.c;other.c;test.c"> <!-- !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! -->
<DisableLanguageExtensions Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">true</DisableLanguageExtensions>
<CompileAs Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">CompileAsC</CompileAs>
</ClCompile>
</ItemGroup>
I then get following compiler and linker warnings:

Is there a way in in msbuild to achive what I like to do: Telling msbuild for each source file what it allowed to use for the compile step?
