How to create a qt gui project with cmake?

Question

Qt

Good day!
There is a graphical application in c++ qt. He originally used qmake.
Then I decided that I needed to switch to cmake. Wrote this cmakelists.txt:

cmakelists.txt

cmake_minimum_required (VERSION 2.6)
project(yourdroid)
option(QT5BUILD "Build using Qt5 libs" TRUE)
# Tell CMake to run moc when necessary:
set(CMAKE_AUTOMOC ON)
# As moc files are generated in the binary dir, tell CMake
# to always look for includes there:
set(CMAKE_INCLUDE_CURRENT_DIR ON)
# Widgets finds its own dependencies (QtGui and QtCore).
find_package(Qt5Widgets REQUIRED)
find_package(Qt5Core)
find_package(Qt5 COMPONENTS Widgets Core REQUIRED)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall")
# The Qt5Widgets_INCLUDES also includes the include directories for
# dependencies QtCore and QtGui
include_directories(${Qt5Core_INCLUDES})
# We need add -DQT_WIDGETS_LIB when using QtWidgets in Qt 5.
add_definitions(${Qt5Widgets_DEFINITIONS})
# Executables fail to build with Qt 5 in the default configuration
# without -fPIE. We add that here.
set(CMAKE_CXX_FLAGS "${Qt5Widgets_EXECUTABLE_COMPILE_FLAGS}")
#qt5_use_modules(yourdroid core gui widgets)
set(yourdroid_SOURCES "data.cpp" "log.cpp" "main.cpp" "window.cpp" "install.cpp" "cmd.cpp" "console.cpp" "bkisofs/bkAdd.c" "bkisofs/bkCache.c" "bkisofs/bkDelete.c" "bkisofs/bkError.c" "bkisofs/bkExtract.c" "bkisofs/bkGet.c" "bkisofs/bkIoWrappers.c" "bkisofs/bkLink.c" "bkisofs/bkMangle.c" "bkisofs/bkMisc.c" "bkisofs/bkPath.c" "bkisofs/bkRead.c" "bkisofs/bkRead7x.c" "bkisofs/bkSet.c" "bkisofs/bkSort.c" "bkisofs/bkTime.c" "bkisofs/bkWrite.c" "bkisofs/bkWrite7x.c")
set(yourdroid_HEADERS "data.h" "log.h" "window.h" "enum.h" "install.h" "version.h" "cmd.h" "console.h" "bkisofs/bk.h" "bkisofs/bkAdd.h" "bkisofs/bkCache.h" "bkisofs/bkDelete.h" "bkisofs/bkError.h" "bkisofs/bkExtract.h" "bkisofs/bkGet.h" "bkisofs/bkInternal.h" "bkisofs/bkIoWrappers.h" "bkisofs/bkLink.h" "bkisofs/bkMangle.h" "bkisofs/bkMisc.h" "bkisofs/bkPath.h" "bkisofs/bkRead.h" "bkisofs/bkRead7x.h" "bkisofs/bkSet.h" "bkisofs/bkSort.h" "bkisofs/bkTime.h" "bkisofs/bkWrite.h" "bkisofs/bkWrite7x.h")
add_executable(yourdroid ${yourdroid_SOURCES} ${yourdroid_HEADERS} ${Qt})

But when compiling, the error "QObject not found" is produced. That is, cmake did not find \\ did not connect QtCore.
Then I found that qt5_use_modules can be used. I inserted qt5_use_modules(yourdroid core gui widgets), but cmake says that the existing target should be the first parameter. Where can I get/create it?
zy In cmake I'm a beginner
zyy I also heard about qt5_wrap_ui, but I didn't even try it because you must first solve that problem
Many thanks in advance! Already smoked all the mana, shoveled the whole Yandex ...

Answer 1

Didn't notice an important detail, qt5_use_modules should be after add_executable, everything worked

Answer 2

I already answered something like this: How to connect qt to cmake?
Start with a minimal project of a couple of files. It will start, add everything else.
