Incorrect path to brew's libarchive on ARM macOS

[alt-romes]

Homebrew's default location for ARM/M-series chips macOSs is /opt/homebrew/opt/libarchive/include (see /opt/homebrew/opt/libarchive/include). This causes the cmake -B build to fail because LibArchive_INCLUDE_PATH is set to the path homebrew uses for Intel macs).

These are the offending lines:

zeal/src/libs/core/CMakeLists.txt

Lines 34 to 36 in de213a7

	if(APPLE AND NOT LibArchive_INCLUDE_DIR)
	set(LibArchive_INCLUDE_DIR "/usr/local/opt/libarchive/include")
	endif()

It would probably be better to get brew's prefix with $(brew --prefix) or to predicate the prefix on the architecture.
I don't know enough CMAKE to do this myself unfortunately.

A quick fix is

export LibArchive_ROOT=/opt/homebrew/opt/libarchive
cmake -S . -B build -G Ninja && cmake --build
