如何使用CMAKE在Linux上交叉编译LuaJIT从而在Windows上使用？

我遇到了一个奇怪的问题。我试图使用CMAKE自动导入、编译和静态链接LuaJIT 2.1-beta3。这个过程在Linux上正常运行，但如果我尝试通过mingw在Windows上进行交叉编译，它就会出错：

make[3]: *** No rule to make target 'install'.  Stop.
make[2]: *** [CMakeFiles/luajit.dir/build.make:74: luajit/src/luajit-stamp/luajit-install] Error 2
make[1]: *** [CMakeFiles/Makefile2:136: CMakeFiles/luajit.dir/all] Error 2
make: *** [Makefile:84: all] Error 2

CMakeLists.txt：

cmake_minimum_required(VERSION 3.0.0)
project(lunar-dreamland VERSION 0.1.0)

include(ExternalProject)

set(luajit_CC "gcc -m32")
if (CMAKE_SYSTEM_NAME MATCHES "Windows")
    ExternalProject_Add(luajit
        URL http://luajit.org/download/LuaJIT-2.1.0-beta3.tar.gz
        PREFIX ${CMAKE_CURRENT_BINARY_DIR}/luajit
        SOURCE_SUBDIR src

        BUILD_IN_SOURCE 1
    )

    ExternalProject_Add(luajit

    )
endif()

add_library(maptick SHARED maptick/dllmain.cpp maptick/sigscan.cpp)
set_target_properties(maptick PROPERTIES COMPILE_OPTIONS "-m32" LINK_FLAGS "-m32")

我使用的工具链文件：

set(CMAKE_SYSTEM_NAME Windows)
set(TOOLCHAIN_PREFIX i686-w64-mingw32)

set(CMAKE_C_COMPILER ${TOOLCHAIN_PREFIX}-gcc)
set(CMAKE_CXX_COMPILER ${TOOLCHAIN_PREFIX}-g++)
set(CMAKE_RC_COMPILER ${TOOLCHAIN_PREFIX}-windres)

set(CMAKE_FIND_ROOT_PATH /usr/${TOOLCHAIN_PREFIX})

set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

如果我从LuaJIT的ExternalProject_Add中除去PREFIX，它会在编译时出错，在 DYNLINK libluajit.so 处，但如果我指定目录，LuaJIT的 make install 仍然会失败。
