QtCreator opened the project, direct error: E: / Qt/Src/Qt - static - Src - 5.14.1 / mkspecs/features/toolchain. PRF (76) : Variable QMAKE_CXX.COMPILER_MACROS is not defined.Project ERROR: msvc-version.conf loaded but QMAKE_MSC_VER isn't set.I did not find a solution and tried to reinstall QtCreator. As a result, the problem was still not well solved.Do you have any way to solve and optimize? Currently, my computer environment is Win7 +Qt5.12+VS2017.
