你这个是编译lua的时候缺少引用，可以这样改：
修改src/CMakeLists.txt文件，找到这一行，大约在166行：

set(CMAKE_EXE_LINKER_FLAGS "-L/usr/lib -L/usr/local/lib")

增加 -lm -ldl ，改成：

set(CMAKE_EXE_LINKER_FLAGS "-L/usr/lib -L/usr/local/lib -lm -ldl")

然后重新make：

make clean;
make

我加了，但是Error还是一样···

按理说编译应该不需要改code才能过吧···所以才怀疑是缺少package导致。问一下你是在什么系统环境下测试的？

恩，这个改动不是code，是cmake的文件。libm是编译lua的依赖，跟zimg没关系。
你试试用apt装一下lua5.1，如果装成功了那说明lua的依赖就全了，然后再编译：

sudo apt-get install lua5.1

还是一样的问题唉···

可能是你虚拟机环境的问题吧，我这也没法帮你调，你自己搜索一下libm.so: error adding symbols: DSO missing (like here)这个问题吧，我看到有很多类似的问题。
zimg的编译经过了travis-ci 和drone.io 的CI验证，他们俩家的CI环境都是Ubuntu，我自己也在Ubuntu14.04虚拟机上测试过了，都没有问题。

终于fix了，感觉是因为系统版本等问题导致找不到那个库。我虚拟机里的应该是64位的版本。
应该是加-lm -ldl来fix，但是那个加的地方不对，改CMAKE_EXE_LINKER_FLAGS是加在了前面：

而正确的做法是加在最后面。所以后来我加到ZIMG_EXTERNAL_LIBS里面就过了···
原来没用过cmake···
多谢~

赞！原来如此，我也没发现是cmake是这么搞的~
update:
已经更新到master分支里了。
