* | configure.ac: fail when ALSA is enabled but not found | Max Kellermann | 2009-03-28 | 1 | -0/+40 |
This patch adds a small autoconf M4 library which deals with auto-detected features. The default for those features is "auto", which is like the old default: if the library is present on the system, enable the feature, disable otherwise. If the user explicitly enables that feature (--enable-alsa), and the library is not present, configure must fail, because it cannot fulfill the request. |
