qt-static-msvc

Automatic travis-ci builds of minimal static version of Qt5 for Windows (for MSVC2017). This allows to build statically-linked binaries which do not require Qt's (or anybody else's) DLLs.

How to use it in Cmake-based Qt project for Windows static builds

The usual Qt stuff in your CMakeLists.txt:

find_package(Qt5 COMPONENTS Widgets Core REQUIRED)
target_link_libraries(**YOUR_TARGET_NAME_HERE** PRIVATE Qt5::Widgets)

"/MT" at the top of CMakeLists.txt

To make your build static, add to the top of your CMakeLists.txt (before add_executable() or other targets):

if (MSVC)
    # /MT means include msvcrt as static library in the .exe
    add_compile_options(/MT)
endif()

In CMake version 3.15 or later you might consider MSVC_RUNTIME_LIBRARY instead.

/INCREMENTAL:NO /NODEFAULTLIB:MSVCRT for each target in CMakeLists.txt:

Add for each of your targets:

if (MSVC)
	target_link_options(**YOUR_TARGET_NAME_HERE** PRIVATE /INCREMENTAL:NO /NODEFAULTLIB:MSVCRT)
end()

(optional) to make sure that your program does not open a console window:

set_target_properties(**YOUR_TARGET_NAME_HERE** PROPERTIES WIN32_EXECUTABLE YES)

Upack the archive downloaded from releases

mkdir C:\Qt
cd /d C:\Qt
7z x qt5.14-static-msvc2017-minimal.zip

This should create C:\Qt\5.14-static-msvc directory

While running CMake, provide appropriate value for Qt5_DIR, e.g.

(in your source dir)
mkdir build
cd build
cmake .. -DQt5_DIR=C:\Qt\5.14-static-msvc\lib\cmake\Qt5
cmake --build .

There you have it: your program linked statically with Qt5.14, even when you use CMake, Windows and MSVC.
