josephg opened issue #11759:

Right now if you try and build for iOS:

cmake -S crates/c-api -B target/c-api --install-prefix "$(pwd)/artifacts" -DWASMTIME_TARGET=aarch64-apple-ios -DWASMTIME_FEATURES="parallel-compilation,pooling-allocator,cranelift,demangle,profiling,coredump,addr2line,winch,pulley"

cmake --build target/c-api
cmake --install target/c-api

The cmake install fails:

CMake Error at target/c-api/cmake_install.cmake:45 (file):
  file INSTALL cannot find
  "/Users/seph/3rdparty/wasmtime/crates/c-api/../../target/aarch64-apple-ios/release/libwasmtime.so":
  No such file or directory.

The problem is this line in CMakeLists.txt:

if(WASMTIME_TARGET MATCHES "darwin")
  set(WASMTIME_SHARED_FILES libwasmtime.dylib)
  set(WASMTIME_STATIC_FILES libwasmtime.a)
elseif(...)

This case should also match for ios, and other apple targets. Changing it to this:

if(WASMTIME_TARGET MATCHES "apple")

Fixes the problem.
