Build process is broken when using -DUSE_ALSA=ON in libpcem.so

[FredBezies]

Describe the bug I wanted to build git code with these options on my Archlinux:

-DUSE_NETWORKING=ON -DUSE_ALSA=ON -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Release .

To Reproduce Steps to reproduce the behavior:

1. Grad latest git commit
2. Use these CMAKE options: -DUSE_NETWORKING=ON -DUSE_ALSA=ON -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Release .
3. Launch build process
4. Wait

Here is the error log I got:

Expected behavior Linking worked and getting a working pcem executable.

It was missing the libraries line to add ASound to the libraries. It will be fixed in the latest commit.

Fixed. Thanks!
