CI artifacts lack licenses for libraries

[Jayman2000]

Descent 3 links to several open-source libraries. At the moment, Descent 3’s CI artifacts don’t comply with those libraries’s licenses. Specifically, they require that you include a copy of the license when distributing the libraries. At the moment, CI artifacts are missing licenses for the following:

Name	Inclusion point	License
libacm	AudioEncode/CMakeLists.txt:6	Link
spdlog	misc/CMakeLists.txt:12	Link
RSA Data Security, Inc. MD5 Message-Digest Algorithm	Descent3/CMakeLists.txt:304	Link

This should be considered "in progress".

• libacm can be included, we have no plans to switch the audio library at the moment
• spdlog may be partially reverted (see Revert "Introduce spdlog logging system" #271) which may change its license terms
• RSA MD5 imho should be changed entirely, see License violation: RSA MD5 comes with an advertising clause twitter/twemproxy#120
• libmve should be added as GPLv2 once Implementing own MVE library #289 is complete

• libacm can be included
• spdlog is now the header only which may have a different license format
• RSA MD5 has been changed so the license is no longer applicable
• libmve will be GPLv2
