Instead of copying the test executable and the JSON files used by
the tests at install time, define CMake/CTest tests for running
the json_unit executable from any build directory with the project's
source directory as its working directory.
- call enable_testing in the main lists file to allow the definition
of tests
- remove install commands from the test directory's lists file
- define two tests
- json_unit_default for running the default tests by executing
json_unit without any arguments
- json_unit_all for running all the tests by executing json_unit
with the "*" argument
- update the AppVeyor configuration file to use the new testing method
Generate the config files of the package in CMAKE_CURRENT_BINARY_DIR
instead of CMAKE_BINARY_DIR because the later will refer to the main
project's binary directory if the library is included in the project
using the add_subdirectory command.
- define the project's version in the cmake listfile
- create a config and config version file for the cmake package
- install the json.hpp file and the package's targets, config and
config version files
Define the library as an interface imported library so other targets
can use the library as a dependency and use the interface properties
of the library.
