【问题描述】：
我正在玩这个项目：https://github.com/chfritz/step2stl
我可以构建它并且运行良好。但是，我正在查看 Makefile，我想知道如何更改它以创建一个静态构建的二进制文件，该二进制文件将在没有安装依赖项的情况下在 linux 机器上运行。
我已经读过在 clang 命令的末尾添加 -static 会起作用，但是我迷失了查看 makefile 并试图弄清楚要更改的内容...
代码如下：
UNAME := $(shell uname -a)
OCEINCLUDE := $(shell if test -d /usr/local/include/oce; then echo "/usr/local/include/oce"; else echo ""; fi)
OPENCASCADEINC?=/usr/include/opencascade

# note that in ubuntu oneiric you will want to use gcc-4.4, since the
# opencascade libraries don't seem wotk work with 4.6 (because they
# were probably compiled with 4.4). on ifab.parc.com i just made 4.4
