c++ - Makefile 在特定系统中失败

Question

在我的项目中，我有以下结构：

.
├── Makefile
├── include
│   ├── Game.h
│   ├── Game.h.gch
│   └── Letter.h.gch
├── letra_A_.png
├── main.cpp
├── modules
│   └── Game.cpp
└── resources
    └── space.bmp

3 directories, 8 files

我的 Makefile 包含：

#Makefile for SDL universe

SOURCES := $(shell find . -name \*.cpp -o -name \*.h)
build:
    echo "Building.."
    g++  -L/usr/include -lSDL2 $(SOURCES) -o blocks
    echo "Done"

我看到的问题是它只能在我拥有的两台机器中的一台机器上工作。运行良好的有 Kali Linux，而失败的有 Ubuntu 18.10。

我可以看到 SDL2 在两个发行版中都安装在相同的位置：

(0) matias #> ls -ldh /usr/include/SDL2/
drwxr-xr-x 2 root root 4.0K Oct 28 11:27 /usr/include/SDL2/

为什么我的项目没有在 Ubuntu 中构建？我收到以下错误：
