如何使用CMAKE从Linux交叉编译适用于Windows的LuaJIT？

我有一个奇怪的问题。我试图通过CMAKE自动拉入、编译和静态链接LuaJIT 2.1-beta3。该过程在linux上运行，但如果我试图通过mingw为Windows交叉编译，则会出现以下错误：

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文件：

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")

如果我从LuaJIT的ExternalProject\u Add中删除前缀，它将在编译时在

DYNLINK libluajit上出错。因此

，但是LuaJIT的

make install

将失败，即使我指定了目录。

Tsyvarev-LuaJIT

make install

目标仅存在于LuaJIT根目录Makefile中。噢，这是子项目的输出，而不是主项目的输出，对不起，这里有噪音。您的

ExternalProject\u Add

调用的Windows版本具有

SOURCE\u SUBDIR src

参数，该参数在Linux版本中不存在。这是有意的区别吗？Tsyvarev--是的，当它尝试在Windows版本上动态链接时，它找不到所有对象文件，这些文件位于

src

中。在构建主项目时，您可以将

VERBOSE=1

参数添加到

make

以查看执行的确切命令行。您是否尝试过直接在mingw终端中执行在没有CMake的情况下构建和安装luajit的命令？
