使用 CMake 在 Windows 上针对 Qt 进行静态链接

Question

我正在开发一个在 Linux 上开发的 Qt 项目，但也有一个静态链接的 Windows 构建。我可以使用相同的 CMakeLists.txt 文件在 Linux 和 Windows 上构建它。它精简为：

project(muckturnier)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_REQUIRED TRUE)
find_package(Qt5 COMPONENTS Widgets Sql)
include_directories(${Qt5Widgets_INCLUDES} ${Qt5Sql_INCLUDES})
set(CMAKE_AUTOMOC ON)
set(muckturnier_SRCS ${CMAKE_CURRENT_SOURCE_DIR}/SomeCode.cpp)
add_executable(muckturnier ${muckturnier_SRCS})
target_link_libraries(muckturnier ${Qt5Widgets_LIBRARIES} ${Qt5Sql_LIBRARIES})

但我还没有设法通过 CMake 在 Windows 上进行静态链接构建。当我手动设置相应的包含目录时，所有构建都很好，但最后我得到一个链接器错误：

这就是我创建 qmake .pro 文件来进行静态构建的原因。这个精简为：

QMAKE_CXXFLAGS += -std=c++11
CONFIG += qt
CONFIG += static
QT += widgets
QT += sql
HEADERS += SomeCode.h
SOURCES += SomeCode.cpp
TARGET = muckturnier

使用 qmake（来自静态 Qt），我可以毫无问题地进行静态构建。所以我的静态 Qt 构建很好，这是一个 CMake 问题。

这是怎么回事？感谢大家的帮助！

我认为您是 this bug 的受害者（仍未解决）。我不是 100% 确定哪里出了问题，但您可以在评论中找到一些想法。
