Qt application is not dynamically linked to windows. What to do?

Question

Qt

There is the following cmake file:

cmake_minimum_required(VERSION 3.1)
project(Flamingo)
set (CMAKE_CXX_STANDARD 14)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_CXX_FLAGS_RELEASE "-O3")
find_package(Qt5Q) find_package(Qt5Q)
find_package(Qt5Q)
find_package(Qt5Multimedia)
find_package(Qt5MultimediaWidgets)
include_directories(".")
file(GLOB_RECURSE Flamingo_SRC
"*.h"
"*.cpp"
"*.hpp"
)
add_executable(${PROJECT_NAME} ${Flamingo_SRC} "res/main.qrc ")
target_link_libraries(${PROJECT_NAME} -lpthread)
target_link_libraries(${PROJECT_NAME} Qt5::Widgets)
target_link_libraries(${PROJECT_NAME} Qt5::Sql)
target_link_libraries(${PROJECT_NAME} Qt5::Multimedia)
target_link_libraries(${PROJECT_NAME} Qt5::MultimediaWidgets)

I use Qt from the off site 5.9.1 version with the MSVC compiler, I compile, everything works, but for some reason windeployqt generates ~ 100MB of files (among them opengl32sw.dll), but it does not add the necessary ones, for example Qt5Sql.dll.
What is the problem? Is there something wrong with my CMakeLists.txt?
UPD: the same project works with qmake. windeployqt generates 50MB of files and everything starts. But still I would like to know why it does not work with cmake

Answer 1

I don’t know if it will help or not, but when I built OpenCV with Qt, I used CMake UI which just highlighted in red that I couldn’t find Qt components. In the same place, I clearly indicated the correct paths and it all worked.
Maybe it makes sense to run CMake UI and see what it swears at?
