Dynamic linking against libbz2 was problematic on some distributions.
We only needed it for pcre's CLI (which we don't use) and ffmpeg's mkv
decompression in case a user forced encoder to use it, because its usage
is discouraged by the standard.
See https://github.com/itgmania/itgmania/issues/217 for the related
discussion.
I was getting the following error when building:
```
fatal: remote error:
The unauthenticated git protocol on port 9418 is no longer supported.
Please see https://github.blog/2021-09-01-improving-git-protocol-security-github/ for more information.
```
Changing the protocol to `https` solves the problem for me.
* macOS build fixes (#1773)
* macOS build fixes
Add missing headers
Threads_Pthreads: do not call pthread_setname_np() on macOS as it does not do
the same as on Linux
DebugStr() -> os_log()
* Make the project build with Makefiles on macOS
* Fix getting modifier key state on Mac (#1774)
We really need to clean up all Carbon calls here (many will go away when the
project switches to SDL2 for all platforms)
* Fix Xcode build; bump minimum version of macOS (#1775)
* Build fixes for the "Unix Makefiles" generator
Pass CMAKE_BUILD_TYPE to the external projects
* Fix indent
The biggest obstacle right now deals with FFMPEG. I insist on being able to utilize the git clone/submodule (5_1_0) section. I'm just struggling with the commands.
As part of this commit, some linux files are restored in the compilation chain. This is for consistency with the old Makefile approach.
Assistance will be needed at this point to complete MinGW support.
