Compiling OpenSonic (Discontinued)

Hello everyone,

I am having problems compiling an old game where binaries and source code are available at: https://sourceforge.net/projects/opensnc/

In the meantime the project has been discontinued and grew into a game scripting called Open Surge.

Error messages running ./configure are as follows. I have been following the way described in the README file.

mwagner@charlie:~/Downloads/opensnc-src-0.1.4> ./configure 
./configure: Zeile 24: allegro-config: Kommando nicht gefunden.
./configure: Zeile 25: allegro-config: Kommando nicht gefunden.
CMake Deprecation Warning at CMakeLists.txt:21 (CMAKE_MINIMUM_REQUIRED):
  Compatibility with CMake < 2.8.12 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

The binaries work fine but they have no sound.

Is there any means to compile this old version?
