For those two build failures the issue is that ?BR2_SHARED_LIBS? is unset, so
Buildroot passes ?-DBUILD_SHARED_LIBS=OFF? to CMake in order to compile only
static libraries. Unfortunately, the brotli CMake files do not respect the
?BUILD_SHARED_LIBS? variable and always build both static+shared libraries.
I have a PR sent upstream, which is being discussed and I'll send soon for
inclusion in Buildroot:

   https://github.com/google/brotli/pull/655

Also, I have discovered that the woff2 package won't build after patching
brotli, for a different reason: It includes a couple of ?FindBrotlidec.cmake?
and ?FindBrotlienc.cmake? files which assume that pkg-config returns a single
library name; but a static build of brotli will have both e.g. libbrotlienc
and libbrotlicommon, so the latter never gets passed to the linker resulting
in missing symbols. I am also working on a patch for this.

If it gets too hairy, I might consider making the brotli package depend on
?BR2_SHARED_LIBS? until a fix is available.

Cheers,
