$ (TargetPath) not calculated when loading a macro?

Question

I have a file custom.propswhere I define the macro that will be used in the project. In this example, I have the following:

<VST2_32_COMMAND_ARGS>$(TargetPath) /noload /nosave /noexc /noft</VST2_32_COMMAND_ARGS>

When I load a project and I look at Properties, Debugging, Argument Arguments, I can access this macro VST2_32_COMMAND_ARGS. But the string is evalutated as/noload /nosave /noexc /noft

In principle, $(TargetPath)not evaluated. In my case, this path points to a DLL, so there should be something like this:

"C:\Program Files (x86)\VstPlugins\Plug\vst2\Win32\bin\MyPlug.dll" /noload /nosave /noexc /noft

But its empty. How can i fix this? Also tried this:

<VST2_32_COMMAND_ARGS>"$(TargetPath)" /noload /nosave /noexc /noft</VST2_32_COMMAND_ARGS>

but the result:

"" /noload /nosave /noexc /noft
