c++ - Windows下Linux下cmake与QT交叉编译

Question

我想在 Windows 下为 Linux 交叉编译一个 cmake 项目。该项目使用QTBase。我做了什么：从官方存储库下载了 QTBase 的源代码。用 i686-mingw 进一步编译。在 cmake 中（我在下面引用）。我包含了推荐的 mingw 文件，它覆盖了编译器的路径（我在下面引用）。应用程序编译成功，但 wine 报告缺少一些库（也在下面）。在 Windows 中，这个编译后的应用程序也无法运行，原因是缺少库。如何正确描述 cmake？

# the name of the target operating system
SET(CMAKE_SYSTEM_NAME Windows)

# Choose an appropriate compiler prefix

# for classical mingw32
# see http://www.mingw.org/
#set(COMPILER_PREFIX "i586-mingw32msvc")

# for 32 or 64 bits mingw-w64
# see http://mingw-w64.sourceforge.net/
set(COMPILER_PREFIX "i686-w64-mingw32")
#set(COMPILER_PREFIX "x86_64-w64-mingw32")

# which compilers to use for C and C++
find_program(CMAKE_RC_COMPILER NAMES ${COMPILER_PREFIX}-windres)
#SET(CMAKE_RC_COMPILER ${COMPILER_PREFIX}-windres)
find_program(CMAKE_C_COMPILER NAMES ${COMPILER_PREFIX}-gcc)
#SET(CMAKE_C_COMPILER ${COMPILER_PREFIX}-gcc)
find_program(CMAKE_CXX_COMPILER NAMES ${COMPILER_PREFIX}-g++)
#SET(CMAKE_CXX_COMPILER ${COMPILER_PREFIX}-g++)


# here is the target environment located
SET(USER_ROOT_PATH /home/erk/erk-win32-dev)
SET(CMAKE_FIND_ROOT_PATH  /usr/${COMPILER_PREFIX} ${USER_ROOT_PATH})

# adjust the default behaviour of the FIND_XXX() commands:
# search headers and libraries in the target environment, search
# programs in the host environment
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

我的笔记：似乎编写了链接器路径，以便应用程序在其文件夹中查找所有 dll。我可以指定在系统文件夹中查找系统 dll 吗？
