QGCS Compilation Error - "Variable QMAKE_CXX.COMPILER_MACROS is not defined."

Hi! I’m getting an error when trying to load QGCS in my system. The error states the following

“Variable QMAKE_CXX.COMPILER_MACROS is not defined.”

I’m running QT 15.5.2 and compiling it using MSVC_2019, but getting this error again n again. I’m new to this so would appreciate any help that your provide.
