Failure to find OpenGL and weird warnings in MSVC 2019

Hello all,
I'm getting some weird errors when using MSVC 2019 to compile and run QT. Namely, the following:

I'm not even sure if they're related to my main problem, which is that visual studio isn't finding any versions of OpenGL. My only idea of a cause is that maybe the MSVC2017 build binaries aren't compatible with MSVC2019 like I initially hoped, but a google search tells me that I should be fine. When I try to create some #ifdefs, I always get the error that I'm throwing in the #else block of the following code:
QSurfaceFormat format; #if defined(QT_OPENGL_ES_3) format = settings->configOpenGLES(); // Configuring format for Open GL ES 3.0 #elif defined(QT_OPENGL_ES_2) throw("Error, Open GL ES 2.0 is not supported by this hardware"); #elif defined(QT_OPENGL) format = settings->configOpenGL(); #else throw("Error, no rendering modes supported by this hardware"); #endifI'm not very familiar with Qt (and am developing on Windows), but I did notice that all versions of Open GL are disabled in my C:\Qt\5.12.2\msvc2017\include\QtGui\qtgui-config.h file. I'm not sure if this is related at all, since that file is just something that ships with Qt.
Lastly, my .pro looks like this:

Edit: Just tried this with MSVC 2017. I'm no longer getting the warnings that I was getting before. However, my check for the QT_OPENGL macro variants is still not working. Any ideas? Is it possible that my system simply does not support open GL ES? If this is the case, how do I develop to support open GL ES?

@feistykittykat Don't know if I'm allowed to bump this bad boy up. Been struggling to use PVRVFrame or something similar to get openGL found on my machine, but I have no idea how to set it up for QT. Still not even sure if that's the source of my problem.
