c++ - Why VS doesn't see included files?

Question

I am a student writing a project. I have created a program (here's the link to SVN: https://mysvn.ru/Ilya_Antonov/antonov_sem_prj). I use CMake to build it and generate the .sln project. But when run it in Visual Studio, there are some errors: the compiler can't open the files "drumswindow.h" and "mainwindow.h" (fatal error C1083). Please, take a look at my CMakeLists.txt:

cmake_minimum_required(VERSION 3.1.0)

project(MusicSimulator VERSION 1.0.0 LANGUAGES CXX)

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_AUTOUIC ON)

if(CMAKE_VERSION VERSION_LESS "3.7.0")
    set(CMAKE_INCLUDE_CURRENT_DIR ON)
endif()


find_package(Qt5 COMPONENTS Gui REQUIRED)
find_package(Qt5 COMPONENTS Widgets REQUIRED)
find_package(Qt5 COMPONENTS Core REQUIRED)
find_package(Qt5 COMPONENTS Multimedia REQUIRED)

add_executable(MusicSimulator
    mainwindow.ui
    mainwindow.cpp
    mainwindow.h
    main.cpp
    drumswindow.ui
    drumswindow.cpp
    drumswindow.h
    keyswindow.ui
    keyswindow.cpp
    keyswindow.h
    images.qrc
    drumres.qrc
    keysres2.qrc
    keysres3.qrc
    keysres4.qrc
    keysres5.qrc
    keysres6.qrc
)

target_link_libraries(MusicSimulator Qt5::Widgets Qt5::Gui Qt5::Core Qt5::Multimedia)

What have I done wrong here?

Answer 1

You don't include the current source dir and therefore the compiler doesn't find it. Either add the current source dir or use the correct include statements (#include "keyswindow.h" for example)
