windows-default build failing with package nng

[desgriff]

I'm running a clean build with VS2019, and am encountering this build issue which has me stumped:

---

EAR Production Suite Base Version: 0.7.3
EAR Production Suite Current Version: 0.7.3.EPS-beta-3-g7743

CMake Error at submodules/vcpkg/scripts/buildsystems/vcpkg.cmake:800 (_find_package):
Could not find a configuration file for package "nng" that is compatible
with requested version "".

The following configuration files were considered but not accepted:

C:/dev/research/audio/ear-production-suite/build/windows-default/vcpkg_installed/x64-windows-static/share/nng/nng-config.cmake, version: 1.5.1 (64bit)

Call Stack (most recent call first):
CMakeLists.txt:44 (find_package)

...I'm guessing either I need nng installed or the package should automatically be pulled down, but this is failing. Any help would be gratefully received.

Hi,
It's not clear from the information in that log, but could this be because you are mixing architectures? (make sure you set your generator to x64 when using the x64-windows-static triplet or any of the Windows CMake presets).
Failing that, it might be helpful to see the contents of build/windows-default/CMakeFiles/CMakeOutput.log and build/windows-default/CMakeFiles/CMakeError.log and we might be able to determine the cause from those. If you don't want to post those on this issue ticket, you could email ear-production-suite-admins@list.ebu.ch
Hope that helps
