| FindJsonCpp |
| ----------- |
| |
| Find JsonCpp includes and library. |
| |
| Imported Targets |
| ^^^^^^^^^^^^^^^^ |
| |
| An :ref:`imported target <Imported targets>` named |
| ``JsonCpp::JsonCpp`` is provided if JsonCpp has been found. |
| |
| Result Variables |
| ^^^^^^^^^^^^^^^^ |
| |
| This module defines the following variables: |
| |
| ``JsonCpp_FOUND`` |
| True if JsonCpp was found, false otherwise. |
| ``JsonCpp_INCLUDE_DIRS`` |
| Include directories needed to include JsonCpp headers. |
| ``JsonCpp_LIBRARIES`` |
| Libraries needed to link to JsonCpp. |
| ``JsonCpp_VERSION_STRING`` |
| The version of JsonCpp found. |
| May not be set for JsonCpp versions prior to 1.0. |
| ``JsonCpp_VERSION_MAJOR`` |
| The major version of JsonCpp. |
| ``JsonCpp_VERSION_MINOR`` |
| The minor version of JsonCpp. |
| ``JsonCpp_VERSION_PATCH`` |
| The patch version of JsonCpp. |
| |
| Cache Variables |
| ^^^^^^^^^^^^^^^ |
| |
| This module uses the following cache variables: |
| |
| ``JsonCpp_LIBRARY`` |
| The location of the JsonCpp library file. |
| ``JsonCpp_INCLUDE_DIR`` |
| The location of the JsonCpp include directory containing ``json/json.h``. |
| |
| The cache variables should not be used by project code. |
| They may be set by end users to point at JsonCpp components. |
