>Description:
Apparently, cmake finds libasound.so (and thus tries to compile with ALSA support), but fails to locate the headers at /usr/local/include/alsa/*. So the build fails. 
>How-To-Repeat:

>Fix:
Disable ALSA support in the Makefile (unset HAVE_LIBASOUND2) or hack the port’s cmake build system to find the ALSA headers in %%LOCALBASE%%.
