Property File's Header Directory Not Being Used

[a_unique_name]

Hello Folks:

Developing on Windows 10 Pro, Visual Studio 2019 Community, Win32, no MFC.

I'm doing something wrong, but I'm not seeing it.

I've recently re-installed Windows 10 Pro on my development system. For some reason Visual Studio appears to be unable to extract a critical directory name from a property file.

Several applications and most libraries I've written depend on the common_cpp_headers property file to point to a directory that contains a collection of headers.

Building one of those libraries displays this problem:



Building the Registry Utilities library can't find some header files.

These header files are in a directory, D:\utilities\code\windows_files\headers, with many other commonly included header files. The Environmental variable UTILITIES_HEADER_PATH points to this directory.

Here are the properties for this property file:



Here is the build config manager for this library.



As you can see, this build is for the debug and Win32 configuration:

Here is the folder being identified by the environmental variable, and the header file name.



There is that directory, identified by the environmental variable, followed by the filename, text_utility.h.

Why can't Visual Studio find it?

Thanks
Larry
