请问如何修改makefile文件？

我下载了一个用源代码方式发布的软件，但要求手动修改makefile文件，作者没有做成自动配置的形式。
我觉得只要改几个变量就可以了，但自己改总是有问题,哪位大侠帮忙改一下。先谢谢了。
我的gcc在/usr/bin目录。

Makefile文件内容如下：
## Available defines for building chm_lib with particular options
# CHM_MT: build thread-safe version of chm_lib
# CHM_USE_PREAD: build chm_lib to use pread/pread64 for all I/O
# CHM_USE_IO64: build chm_lib to support 64-bit file I/O
#
# Note: LDFLAGS must contain -lpthread if you are using -DCHM_MT.
#
#CFLAGS=-DCHM_MT -DCHM_USE_PREAD -DCHM_USE_IO64
CFLAGS=-DCHM_MT -DCHM_USE_PREAD -DCHM_USE_IO64 -g -DDMALLOC_DISABLE
LDFLAGS=-lpthread
