Cmake: Could not find a package configuration file provided by "nlohmann_json"

[Willard Nilges]

Getting an error at the cmake .. step in the build instructions:

CMake Error at driver/overlay/CMakeLists.txt:1 (find_package):
  Could not find a package configuration file provided by "nlohmann_json"
  with any of the following names:

    nlohmann_jsonConfig.cmake
    nlohmann_json-config.cmake

  Add the installation prefix of "nlohmann_json" to CMAKE_PREFIX_PATH or set
  "nlohmann_json_DIR" to a directory containing one of the above files.  If
  "nlohmann_json" provides a separate development package or SDK, be sure it
  has been installed.

Guessing a new package or submodule was added?

Looking at this to try to fix it: nlohmann/json#1573

I think you've figured this out already, but you need to have vcpkg installed to get these libraries 😁
