Eu tenho um CMakeLists.txt simples que se parece com isso:

   CMAKE_MINIMUM_REQUIRED(VERSION 2.8)

   PROJECT(calculator)

   FIND_PACKAGE(Qt5Core)
   FIND_PACKAGE(Qt5Gui)
   FIND_PACKAGE(Qt5Widgets)

   SET(CMAKE_AUTOMOC ON)
   SET(CMAKE_INCLUDE_CURRENT_DIR ON)

   SET(calculator_SOURCES main.cpp mainwindow.cpp)
   SET(calculator_HEADERS mainwindow.h)
   SET(calculator_FORMS mainwindow.ui)

   QT5_WRAP_CPP(calculator_HEADERS_MOC ${calculator_HEADERS})
   QT5_WRAP_UI(calculator_FORMS_HEADERS ${calculator_FORMS})

   ADD_LIBRARY(calculator_CONFIG ${calculator_HEADERS_MOC} ${calculator_FORMS_HEADERS})
   QT5_USE_MODULES(calculator_CONFIG Widgets)

   ADD_EXECUTABLE(calculator ${calculator_SOURCES} ${calculator_CONFIG})
   QT5_USE_MODULES(calculator Core Gui Widgets)

E quando eu tento construir o projeto usandocmake -G "Unix Makefiles" e subsequentementemake, o console diz queui_mainwindow.h Não foi encontrado. Qual é o problema? É o meu arquivo cmake?

Saída de erro completa:
