ESP8266 -- Linked resources not included in derived makefile [message #1801980]

I am trying to return to using Eclipse to build some ESP8266 projects. I have a project that worked some time back on oxygen, but I've long since lost the setup I used. I'm still pretty new to all of this, so I would appreciate any help here as I've been at this for a couple days now :)

I've installed the latest Eclipse (2018-12) and the Eclipse C++ IDE for Arduino 3.0. I have the ESP8266 platform installed. I have created a new Arduino project and pulled the source code files from my old project forward.

I have a list of issues, but the one I haven't been able to work around yet is that linked resources are not being pulled into the derived makefile that is created for the project. Thus when I go to build, the build fails.

Here is the failing step:

If I modify this command by adding these includes, the command will complete successfully:
-I"C:/Users/TJ/.arduinocdt/libraries/ArduinoJson/5.13.4/src" -- Workaround as I can't get the library manager to install old lib version
-I"F:/Users/TJ/Arduino/libraries/ConfigFile" -- Custom library used by other projects
-I"F:/Users/TJ/Arduino/libraries/Door" -- Custom library used by other projects
-I"F:/eclipse-workspace/GarageDoorSecure" -- The project workspace itself. Very strange I have to add this I would think

Here is the command from the cmd prompt running succesfully with the three includes above:

F:\eclipse-workspace\GarageDoorSecure\build\Esp8266>

These includes are all included in the project -- the first three via linked resources, and the last one in the project root itself:

Note the ConfigFile.h header that caused the above failure is showing in the linked resource.

If this were a standard C++ project, I would just add these through the preprocessor includes in the project settings. However, Arduino projects do not seem to have this option:

I could directly edit the makefile, but this is autogenerated and I also can't find a way to disable automatic makefile generation on an Arduino project. It would also be a major pain considering the problem seems very straightforward.

Could anyone give some pointers on how to fix this issue the right way? I don't understand how to ensure my linked resources make it into the makefile. It seems the Eclipse indexer finds them fine as I can access them while editing the code, but the makefile/compiler is never able to find them.

Thanks in advance, I would greatly appreciate any information :)
