Qt Creator produces "No such file or directory" error with existing file

No, that is the work of DEPENDPATH. INCLUDEPATH is for includes only. But this has no influence on your current situation.

.pro.user file is not used for compilation. It merely contains QtCreator settings (of course including settings for running the compiler, but it only states which compiler to run (by passing options to qmake that parses the .pro file), not what directories it should search for include files). The .pro file controls compilation process.

Well, how do you explain then that once the .pro.user file got rewritten and I removed the INCLUDEPATH statement from the .pro file, and tried to build, I'm no longer getting the "No such file or directory" error?

I will not even try explaining that. I could if I had contents of both your projects so that I could compare them (especially the .pro files). I just know how both QtCreator and compilers work and I know the error such as you got is not caused by QtCreator.
