Thanks for your work taking care of flac.

I think a build system proliferation as FOSS is used on more platforms 
than expected is a bit of a rite of passage for projects started longer 
than 10 years ago.  Libwebsockets grew in a similar way, make, replaced 
by autotools, then msvc project files that were contributed and 
incompatible by msvc version, finally cmake.  Even, eg, mbedtls and 
wolfssl suffer something similar, they ship with both autotools and 
cmake, but the two are not in sync for options (or sometimes even 
agreeing on the list of sources and being able to build at all in 
mbedtls + cmake case).  There's a lot of evidence this approach is not 
really maintainable.

Libwebsockets moved entirely to cmake five or six years ago, dropping 
the other options and it has been great, it also provides ctest to 
provide crossplatform testing instead of the nest of nonportable bash 
scripts we had before.  In the meanwhile everything else like Android 
build, msvc as you mentioned, iOS, bsds, solaris, cross-build... either 
has first-class cmake support or is now completely predicated around it. 
  CMake won the argument a long time ago.

So I would suggest that making a new release dropping everything except 
cmake is the best way to maintain this.
