I've seen this asked many times, but with no real concrete answer. How do I compile my Qt Creator project with statically linked libraries?
My project is really simple. It's just a calculator, so I really don't think it needs to link much stuff.
My CMakeLists.txt file (there really isn't any change to this file, it's just the auto-generated one by Qt Creator):
cmake_minimum_required(VERSION 3.5)
project(Calculator VERSION 0.1 LANGUAGES CXX)
set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
find_package(QT NAMES Qt6 Qt5 REQUIRED COMPONENTS Widgets)
find_package(Qt${QT_VERSION_MAJOR} REQUIRED COMPONENTS Widgets)
set(PROJECT_SOURCES
main.cpp
calculator.cpp
calculator.h
calculator.ui
)
if(${QT_VERSION_MAJOR} GREATER_EQUAL 6)
qt_add_executable(Calculator
MANUAL_FINALIZATION
${PROJECT_SOURCES}
)
# Define target properties for Android with Qt 6 as:
# set_property(TARGET Calculator APPEND PROPERTY QT_ANDROID_PACKAGE_SOURCE_DIR
# ${CMAKE_CURRENT_SOURCE_DIR}/android)
# For more information, see https://doc.qt.io/qt-6/qt-add-executable.html#target-creation
else()
if(ANDROID)
add_library(Calculator SHARED
${PROJECT_SOURCES}
)
# Define properties for Android with Qt 5 after find_package() calls as:
# set(ANDROID_PACKAGE_SOURCE_DIR "${CMAKE_CURRENT_SOURCE_DIR}/android")
else()
add_executable(Calculator
${PROJECT_SOURCES}
)
endif()
endif()
target_link_libraries(Calculator PRIVATE Qt${QT_VERSION_MAJOR}::Widgets)
set_target_properties(Calculator PROPERTIES
MACOSX_BUNDLE_GUI_IDENTIFIER my.example.com
MACOSX_BUNDLE_BUNDLE_VERSION ${PROJECT_VERSION}
MACOSX_BUNDLE_SHORT_VERSION_STRING ${PROJECT_VERSION_MAJOR}.${PROJECT_VERSION_MINOR}
MACOSX_BUNDLE TRUE
WIN32_EXECUTABLE TRUE
)
if(QT_VERSION_MAJOR EQUAL 6)
qt_finalize_executable(Calculator)
endif()

If this is even important to mention, I want to build two static executables, one for Linux and one for Windows. What do I need to add to do this?
You have to first build the static libraries. Qt doesn't (or at least didn't, last I checked) distribute static libraries. Be prepared for an exercise when doing this for Windows. There's a Wiki, but it's flawed.
Also, note that using static Qt libraries is covered under a more restrictive license. You'll have to check Qt's site for details on this.
