Qt5.9.1 + MSVC2017 64bit编译器开发时的错误：
jom: D:GitHubAppMakefile.Release [releasedoAction.obj] Error 2
jom: D:GitHubAppMakefile [release] Error 2
16:08:04: The process "C:QtQt5.9.1ToolsQtCreatorinjom.exe" exited with code 2.
Error while building/deploying project App (kit: Desktop Qt 5.9.1 MSVC2017 64bit)
When executing step "Make"
解决过程：
Tools => Options => Build & Run => Qt 5.9.1 MSVC2017 64bit => Compiler: C/C++ Microsoft Visual C++ compiler 15.0 (x86_amd64) 之前是Microsoft Visual C++ compiler 15.0 (amd64)
