是什么导致我的CMake多目标模式错误？

问题描述 投票：0回答：1

我一直在尝试在代码块上安装box2D 2.3。一切进展顺利，直到我遇到了.make文件的障碍。我相信大多数问题是由代码块使用“ \”而不是“ /”作为文件路径引起的。但是，由于出现错误，我被卡住了：

||=== Build: all in Box2D (compiler: GNU GCC Compiler) ===|
Box2D\CMakeFiles\Box2D.dir\build.make|803|*** multiple target patterns.  Stop.|
CMakeFiles\Makefile2|96|recipe for target 'Box2D/CMakeFiles/Box2D.dir/all' failed|
C:\Users\111\Documents\C++ Libraries\box2d-2.3.0\box2d-2.3.0\Box2D\Build\Makefile|82|recipe for target 'all' failed|
||=== Build failed: 3 error(s), 0 warning(s) (0 minute(s), 1 second(s)) ===|

第803行：

@$(CMAKE_COMMAND) -E cmake_echo_color --switch=$(COLOR) --green --bold --progress-dir="C:/Users/151/Documents/C++ Libraries/box2d-2.3.0/box2d-2.3.0/Box2D/Build/CMakeFiles" --progress-num=$(CMAKE_PROGRESS_47) "Linking CXX static library libBox2D.a"

这是可能会导致.make文件错误的相关代码块。

我在示例makefile文件中看不到任何反斜杠，所以我认为这不是问题。
