   +1 from the Spack package manager side. Now that we're seeing other things like HPX 2.x creating dependencies on this there will be increased interest and more patching needed. I've seen cpm being used and failing various use cases in Legion/Realm, so we eventually added the necessary fallbacks to support other packaging efforts. @junghans @hkaiser FYI

   +1 for Fedora packaging.

   As stdexec is header-only, and all dependencies are used for testing only a simple_install.sh as below should do the same as the cmake --install:

   #! /bin/sh -e
   
   [ -d "$1" ] || { echo "First argument should be a directory"; exit 1; }
   
   # exclude asio sub directory
   find include/exec -path "include/exec/asio" -prune -o -type f -exec install -D -m 0644 {} "$1"/{} \;
   find include/stdexec -type f -exec install -D -m 0644 {} "$1"/{} \;
   
   cat << EOF > "$1"/include/stdexec_version_config.hpp

   No testing, of course.

   +1 from the Conan side. I opened #2341 as a small first step. It keeps CPM and icm out of the default configure, so stdexec can be configured and installed without network access when tests and the optional integrations are off. It doesn't change how the integrations get their dependencies, which is the rest of what this issue asks for.

   I also opened #2342 asking for a v0.11.0 tag, so package managers don't have to make up their own versions.

   @czoido After chatting with @rbberger yesterday, we came with a similar approach (details below). #2341 is the more complete version of that, so thanks for creating the PR.

   For Fedora, I got it to package, but I still need to figure out what to do with the bundled rapids-cmake though. At least one can pre-download that and then inject it with -Drapids-cmake-url=file://....

   Thanks @junghans and @rbberger, good sign that we landed on the same fix! The extra conditions in #2341 are there because the ASIO, Taskflow and CUDA integrations also use CPM (rapids_cpm_find, CPMAddPackage and rapids_cpm_cccl), and rapids_cpm_init has to run before them.

   For rapids-cmake, the idea for the ConanCenter recipe would be to point CMake's standard FETCHCONTENT_SOURCE_DIR_RAPIDS-CMAKE variable at an unpacked copy of the archive, in case that's easier for Fedora than a file:// URL.

   I just did

   Source1:        https://github.com/rapidsai/rapids-cmake/archive/refs/heads/branch-24.02.zip
   ...
   %cmake -DSTDEXEC_BUILD_TESTS=OFF -Drapids-cmake-url=file://%{S:1}
   ...

   which works in a network-less build as well.

   Great progress! Thanks for getting it done.

   @ericniebler The only leftover nitpick is that include/._clangd_helper_file is compiled for nothing.
   This is not a problem most of times, however, if for whatever reason you're untar-ing this repo on MacOS (like when using a cached git-clone) the ._ file may be mistaken as AppleDouble metadata file and skipped, causing a hard compilation error due to missing files. Created a dedicate issue for this: #2345
