There are no precompiled libraries for any platform. The release package
just contains source code.

I just mean that AFAIK there are no binary libraries for iOS on your website. 
(Right?)

I did discover that I can run `cmake -G Xcode .` and CMake will generate an 
Xcode project file. Then I was able to change a few build settings in the 
project and get Xcode to build iOS static libs. I haven’t actually tested them 
yet, but this looks like a promising approach, even if it’s not as turn-key as 
just running CMake in my top-level project directory.

Do you mean that iOS was broken at the last release, but has been fixed at
master since then? (I don't know how to test iOS so I have no idea which
versions work or not...)

The instructions are not out of date. autotools is still considered to be
the preferred build system, but cmake files have been contributed. I don't
personally understand cmake so these files are maintained by other
contributors.

(Unfortunately that means I don't know the answer to your question...)

[capnproto] Building with CMake

[Jens Alfke]

I want to build Cap’n Proto from source as part of my project; I know it’s 
preferred to download a release, but I need to support iOS and there are no 
releases for that AFAIK.

The build instructions at https://capnproto.org/install.html 
 seem out of date; they say to use 
autoconf, but the current sources have a CMakeFile and I found that the usual 
CMake build command work fine:
mkdir build_cmake && cd build_cmake
cmake ..
make

However, if I add capnproto as a subdirectory to my project’s CMakeLists.txt:
add_subdirectory(vendor/capnproto)
it doesn’t build. During the initial ‘cmake’ command for my project, I get 
several errors of the form:

CMake Error at vendor/capnproto/c++/cmake/CapnProtoMacros.cmake:106 
(add_custom_command):
  Error evaluating generator expression:

$

  No target "CapnProto::capnp_tool"
Call Stack (most recent call first):
  CMakeLists.txt:113 (capnp_generate_cpp)

I have no idea what this means, or what to do about it…
