[CMake] 'NMake Makefiles' generate does not support parallel builds (/MP)?

[Loaden]

Because I want share the MSVC's PCH files, so I have to set the compile PDB
name:

>     get_filename_component(pdbpath ${${targetBinary}_PCH_BINARY_FILE} PATH)
>     get_target_property(targetCompileFlags ${targetSelf} COMPILE_FLAGS)
>     if (targetCompileFlags)
>         set(origCompileFlags ${targetCompileFlags})
>     endif()
>     set_target_properties(${targetSelf} PROPERTIES
>         COMPILE_FLAGS "${origCompileFlags}
> /Fd\"${pdbpath}/${targetBinary}.pdb\""
>     )
>

For NMake Makefiles generator, it works after change:

>     string(REGEX REPLACE " /Fd<TARGET_PDB>" "" temp
> "${CMAKE_${${targetBinary}_PCH_LANGUAGE}_COMPILE_OBJECT}")
>     set(CMAKE_${${targetBinary}_PCH_LANGUAGE}_COMPILE_OBJECT ${temp}
> PARENT_SCOPE)
>

It mean I can change the PDB file name using a hacking way:

> *string(REGEX REPLACE " /Fd<TARGET_PDB>" "" CMAKE_CXX_COMPILE_OBJECT
> "${CMAKE_CXX_COMPILE_OBJECT}")*
>
But it does not work with Ninja generator.

Could you please give me any tips?
I look into the build.ninja file, and see there are many "TARGET_PDB =
XXX.pdb" lines.
The PDB file is hard code  to target name.

So, the question may be changed to: How to change the PDB file name of
Ninja generator?

I read the rules.ninja file too, there seems exist a rules for compilation.
But I don't know how to change the rules.

Thanks for any comments / helps.
