Fedora package links to system CEF instead of bundling it

Fedora's system CEF version is 146.0.11 so we choose the Dullahan
version that uses the next closest CEF version (146.0.12 and not
146.0.10), which is Dullahan 1.29 and not 1.28.
System libcef_dll is somehow distributed only in source form
(on Arch too), so in order to be able to link to it, we have to
compile it first, but its CMakeLists.txt is a sub one, incomplete,
so we use the solution of adding an empty macro:
https://www.magpcss.org/ceforum/viewtopic.php?f=6&t=17732
System CEF's library encapsulating folder that contains libcef.so,
hence needs to be add to runtime path.
