json-schema-validator/test/cmake-install/project/CMakeLists.txt
Luke Kersting 8a7d1d3fde Adapt CMake project name to be coherent with nlohmann::json's naming
Now when json-schema-validator is installed CMake config files are installed in the lib/cmake/json-schema-validator directory.
The install json-schema-validatorTargets.cmake file properly imports the json-hpp and json-schema-validator libraries.
The install json-schema-validatorConfig.cmake file is used by CMake find_package function to include the json-schema-validatorTargets.cmake file and to set the variable JSON_SCHEMA_VALIDATOR_INCLUDE_DIRS to the install include directory.
To use find_package to find the json-schema-validator simply include.
A new test (test_cmake_install) has been added.

When NLohmann's JSON is install with CMake, it follows a certain
naming convention.

As we learned to do proper CMake-install thanks to @lkersting's work
this project now adapts to the way NLohmann is doing it. Namely:

- json-schema.hpp is now located (and installed)
  in a nlohmann/-subdirectory
- the CMake library and project's name is now
  nlohmann_json_schema_validator

Instead of doing non-standard acrobatics to find the json.hpp
now find_package is used in order to find NLohmann's package
