FindSQLite3
-----------
.. versionadded:: 3.14
Finds the SQLite 3 library:
.. code-block:: cmake
find_package(SQLite3 [<version>] [...])
SQLite is a small, fast, self-contained, high-reliability, and full-featured
SQL database engine written in C, intended for embedding in applications.
Imported Targets
^^^^^^^^^^^^^^^^
This module provides the following :ref:`Imported Targets`:
``SQLite::SQLite3``
Target encapsulating SQLite library usage requirements. It is available only
when SQLite is found.
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables:
``SQLite3_FOUND``
Boolean indicating whether the (requested version of) SQLite library was
found.
``SQLite3_VERSION``
The version of SQLite library found.
``SQLite3_INCLUDE_DIRS``
Include directories containing the ``<sqlite3.h>`` and related headers
needed to use SQLite.
``SQLite3_LIBRARIES``
Libraries needed to link against to use SQLite.
Examples
^^^^^^^^
Finding the SQLite library and linking it to a project target:
.. code-block:: cmake
find_package(SQLite3)
target_link_libraries(project_target PRIVATE SQLite::SQLite3)
