[Ubuntu] OpenGL Super Bible 6th 예제를 빌드하려다 보면..#1. alienrain.cpp: undefined reference to ~ 에러

Ubuntu에서 

OpenGL Super Bible 6th 예제들을 돌려보려 하다보면 HOWTOBUILD.txt 에 있는 내용대로 따라하더라도

alienrain.cpp 파일을 빌드하면서 부터 시작해서 undefined reference to ~~ 빌드 에러가 주욱 나올 것이다.

(에러로그는 하단에)

지난 주말간 삽질한 결과로 해결방법은 찾을 수 있었는데

원인은 sb6code-master/CMakeList.txt에 잘못 작성된 버그라 한다.

그래서 CMakeLists.txt 파일의 13번째 line에 있는 elif(UNIX)를 elseif(UNIX)로 고치면 

정상적으로 빌드가 진행된다.
