Build is failed on alpine linux, probably musl compatibility.

Hello, I'm trying to build on alpine linux. cmake .. didn't produce miracle-wm binary. I tried using these commands instead :

$ cmake -B build
$ cmake --build build

Then I got these error messages :

  8%] Building CXX object CMakeFiles/miracle-wm.dir/src/window_tree.cpp.o

gmake: *** [Makefile:136: all] Error 2

Any clue to fix it ?

Also I need to comment main.cpp at line 60, if I don't I will get this error :

Perhaps it has something to do about musl compatibility.

It looks to me like mir is on a previous version here, as X11Support{}.default_to_enabled() should be in latest (maybe as of 2.16 or earlier).

The floorf issue is most likely an actual break though

Closing this as it should be fixed, but let me know!
