Previously (February 2023), the ziti-tunnel-sdk-c build would automatically fetch and compile dependencies. Attempting a cross-compile build today (May 5th), the process fails, reporting: > using Unix Makefiles > cross-compiling FALSE > Project: tlsuv@v0.23.1 > CMake Error at build-amd64/\_deps/tlsuv-src/CMakeLists.txt:75 (find\_package): > Could not find a package configuration file provided by "llhttp" with any > of the following names: > > ``` > llhttpConfig.cmake > llhttp-config.cmake > > ``` > > Add the installation prefix of "llhttp" to CMAKE\_PREFIX\_PATH or set > "llhttp\_DIR" to a directory containing one of the above files. If "llhttp" > provides a separate development package or SDK, be sure it has been > installed. > > -- Configuring incomplete, errors occurred! > See also "/mnt/build-amd64/CMakeFiles/CMakeOutput.log". Are there revised build instructions someone can point me to? ---

Hi @tomc, Welcome to the community! Thanks for the feedback. The ziti-tunnel-sdk-c repo is most definitely in a state of flux… The ziti-sdk-c was updated to use vcpkg and it’s causing a wee bit of churn for people, for sure. We don’t have anything written up yet, but I’m sure we can get you building again until we settle it out… @scareything or @ekoby anything else you want to add? @tomc what OS are you building on and targetting? ---

Thanks. I’ll get you a short list of commands after I make sure they work and shoot them over. ---

Ok here’s a condensed list of steps… I just used these locally. ```auto export VCPKG_ROOT=/path/to/where/you/want/to/put/vcpkg mkdir -p $VCPKG_ROOT git clone git@github.com:microsoft/vcpkg.git $VCPKG_ROOT sudo apt install zip -y sudo apt-get install pkg-config -y $VCPKG_ROOT/bootstrap-vcpkg.sh cd /to/wherever/you/have/ziti-tunnel-sdk-c/ mkdir build cd build cmake --preset ci-linux-x64 .. cmake build . ``` Note that cmake will now require you have env var VCPKG\_ROOT and it’s expected that this is the root of the vcpkg checkout (as shown in the steps listed above). Stating the obvious, but most of these are ‘one-time’ steps you’ll need to run. You can also read up on vcpkg presets if you’re interested or need to change away from the ‘ci-linux-x64’ preset. The first time you do this Hope that helps! ---

fyi the file [HACKING.md](https://github.com/openziti/ziti-tunnel-sdk-c/blob/main/HACKING.md) talks about the conventional way to define your own presets, which may inherit from the presets in CMakePresets.json. Note I’ve seen the `"$comment"` field confuse some versions of cmake, so I’d omit that line from your preset file. ---

Stumbled upon this very issue and lo- the answer be-ith here! I utilize a little utility I wrote for automation of openwrt building. ([NetFoundry/Utilities/OpenZITI-OWRT at main · NicFragale/NetFoundry · GitHub](https://github.com/NicFragale/NetFoundry/tree/main/Utilities/OpenZITI-OWRT)) and I’ll be making the appropriate update there to it as well. Thanks for asking this @tomc, and thank you for the answer @TheLumberjack ! ---
