| FindODBC | ||
| -------- | ||
|
|
||
| Find an Open Database Connectivity (ODBC) include directory and library. | ||
|
|
||
| On Windows, when building with Visual Studio, this module assumes the ODBC | ||
| library is provided by the available Windows SDK. | ||
|
|
||
| On Unix, this module allows to search for ODBC library provided by | ||
| unixODBC or iODBC implementations of ODBC API. | ||
| This module reads hint about location of the config program: | ||
|
|
||
| .. variable:: ODBC_CONFIG | ||
|
|
||
| Location of odbc_config or iodbc-config program | ||
|
|
||
| Otherwise, this module tries to find the config program, | ||
| first from unixODBC, then from iODBC. | ||
| If no config program found, this module searches for ODBC header | ||
| and library in list of known locations. | ||
|
|
||
| Imported targets | ||
| ^^^^^^^^^^^^^^^^ | ||
|
|
||
| This module defines the following :prop_tgt:`IMPORTED` targets: | ||
|
|
||
| .. variable:: ODBC::ODBC | ||
|
|
||
| Imported target for using the ODBC library, if found. | ||
|
|
||
| Result variables | ||
| ^^^^^^^^^^^^^^^^ | ||
|
|
||
| .. variable:: ODBC_FOUND | ||
|
|
||
| Set to true if ODBC library found, otherwise false or undefined. | ||
|
|
||
| .. variable:: ODBC_INCLUDE_DIRS | ||
|
|
||
| Paths to include directories listed in one variable for use by ODBC client. | ||
| May be empty on Windows, where the include directory corresponding to the | ||
| expected Windows SDK is already available in the compilation environment. | ||
|
|
||
| .. variable:: ODBC_LIBRARIES | ||
|
|
||
| Paths to libraries to linked against to use ODBC. | ||
| May just a library name on Windows, where the library directory corresponding | ||
| to the expected Windows SDK is already available in the compilation environment. | ||
|
|
||
| .. variable:: ODBC_CONFIG | ||
|
|
||
| Path to unixODBC or iODBC config program, if found or specified. | ||
|
|
||
| Cache variables | ||
| ^^^^^^^^^^^^^^^ | ||
|
|
||
| For users who wish to edit and control the module behavior, this module | ||
| reads hints about search locations from the following variables: | ||
|
|
||
| .. variable:: ODBC_INCLUDE_DIR | ||
|
|
||
| Path to ODBC include directory with ``sql.h`` header. | ||
|
|
||
| .. variable:: ODBC_LIBRARY | ||
|
|
||
| Path to ODBC library to be linked. | ||
|
|
||
| These variables should not be used directly by project code. | ||
|
|
||
| Limitations | ||
| ^^^^^^^^^^^ | ||
|
|
||
| On Windows, this module does not search for iODBC. | ||
| On Unix, there is no way to prefer unixODBC over iODBC, or vice versa, | ||
| other than providing the config program location using the ``ODBC_CONFIG``. | ||
| This module does not allow to search for a specific ODBC driver. | ||
