Compile SC from GitHub "Open with Visual Studio"

Is it possible to use the “Open with Visual Studio” option on GitHub to successfully compile SC? If so, what am I doing wrong?

I would like to compile the SC code and make a build of SC with the hope of eventually contributing to
SC. On the GitHub SC repo, I noticed that under the code button there is an “Open with Visual Studio” option. I chose this option and was able to get to a point where cmake would give me this error:

Severity	Code	Description	Project	File	Line	Suppression State
Error		CMake Error at QtCollider/CMakeLists.txt:30 (find_package):
  By not providing "FindQt5.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Qt5", but
  CMake did not find one.

  Could not find a package configuration file provided by "Qt5" (requested
  version 5.7) with any of the following names:


  Add the installation prefix of "Qt5" to CMAKE_PREFIX_PATH or set "Qt5_DIR"
  to a directory containing one of the above files.  If "Qt5" provides a
  separate development package or SDK, be sure it has been installed.		C:\Users\pedro\Source\Repos\supercollider\QtCollider/CMakeLists.txt	30	

I see that the instructions in require Qt >= 5.7
The Qt installer offers 5.9.9, but there is no MSVC 2019 option, only earlier and they did not seem to work.
I saw another post on here which said that Qt 5.15 works, but that post is a year old.
I went with Qt 5.15.2 and MSVC 2019 64-bit.

I then added the following set() commands in the offending CMakeLists.txt file, which did not change the error message.


set(Qt5_DIR C:\Qt\5.15.2\msvc2019_64\lib\cmake\Qt5)

(I tried each set command individually and put them under the above find_packages line.)
