iOS/Android support about libsql HOT 6 OPEN

I successfully ran libsql on Android. I don't think I had to do anything special. What I do though is having a new Rust lib project that depends on libsql.

from libsql.

Running lipo on the generated .a for x86_64 allowed me to pin point the problem:

lipo -info ../../target/x86_64-apple-ios/release/libsql_experimental.a                                                                                   
fatal error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/lipo: archive member ../../target/x86_64-apple-ios/release/libsql_experimental.a(sqlite3mc.c.o) cputype (16777228) and cpusubtype (0) does not match previous archive members cputype (16777223) and cpusubtype (3) (all members must match)

Indeed it seems the cargo build is targeting apple ios x86_64 but the generated sqlite object file has been compiled for another arch. Looking at the build script I find nothing weird. The cc crate is used for compiling the sqlite source file which should handle cross compilation gracefully. So it seems this path with a cmake build is happening (maybe due the encryption feature being turned on?).

I've added the following to try to make cross compilation work, but it doesn't seem to be doing anything:

if target.contains("x86_64-apple-ios") {
    cmake_opts.push(&cmake_toolchain_opt);
    writeln!(toolchain_file, "set(CMAKE_SYSTEM_NAME \"iOS\")").unwrap();
    writeln!(toolchain_file, "set(CMAKE_SYSTEM_PROCESSOR \"x86_64\")").unwrap();
}

Edit: turning off the encryption feature does indeed allow the crate to compile successfully. Seems indeed the cmake compilation is off for non-host architectures.
