Create an install target for the project - 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 2016-04-25 08:23:14 +00:00			`@PACKAGE_INIT@`
Enable target namespaces and build dir project config CMake convention is to use a project namespace, i.e. Foo::, for imported targets. When multiple targets are imported from a project, this looks like Foo::Bar1 Foo::Bar2, etc. This adds the nlohmann_json:: namespace to the exported target names. This also allows the generated project config files to be used from the build directory instead of just the install directory. 2018-04-09 15:32:18 +00:00			`if(NOT TARGET @PROJECT_NAME@::@NLOHMANN_JSON_TARGET_NAME@)`

Use a version check to provide backwards comatible imported target names. 2018-09-18 17:59:19 +00:00			`if((NOT TARGET @NLOHMANN_JSON_TARGET_NAME@) AND`

REFACTOR: rewrite CMakeLists.txt for better inlcude and reuse The rewrite uses more cmake build-in automatisms and build-in generates variables to allow better generic reuse. * cmake files are installed to ``` <install_prefix>/lib/cmake/nlohmann_json/ ``` for best support on most systems * include path is set to ``` include ``` for usage as ``` #include <nlohmann/json.hpp> ``` 2017-07-29 09:59:09 +00:00			`check_required_components("@PROJECT_NAME@")`
