FindIntl

Added in version 3.2.

Finds internationalization support that includes message translation functions such as gettext(). These functions originate from the GNU libintl library, which is part of the GNU gettext utilities, but may also be provided by the standard C library.

Imported Targets

This module provides the following Imported Targets:

Intl::Intl

Added in version 3.20.

Target encapsulating the Intl usage requirements, available if Intl is found.

Result Variables

This module defines the following variables:

Intl_FOUND

Boolean indicating whether the Intl is found.

Intl_INCLUDE_DIRS

Include directories containing headers needed to use Intl.

Intl_LIBRARIES

The libraries needed to link against to use Intl.

Intl_VERSION

Added in version 3.21.

The version of the found Intl implementation or library, in the format x.y.z.

Note

Some Intl implementations don't embed the version in their header files. In this case the variables Intl_VERSION* will be empty.

Intl_VERSION_MAJOR

Added in version 3.21.

The major version of Intl found.

Intl_VERSION_MINOR

Added in version 3.21.

The minor version of Intl found.

Intl_VERSION_PATCH

Added in version 3.21.

The patch version of Intl found.

Cache Variables

The following cache variables may also be set:

Intl_INCLUDE_DIR

The directory containing the libintl.h header file.

Intl_LIBRARY

The path to the Intl library (if any).

Intl_IS_BUILT_IN

Added in version 3.20.

Boolean indicating whether the found Intl functionality is provided by the standard C library rather than a separate libintl library.

Note

On some platforms, such as Linux with GNU libc, the gettext functions are present in the C standard library and libintl is not required. The Intl_LIBRARY and Intl_INCLUDE_DIR will be empty in this case.

Examples

Finding the Intl support and linking the imported target for use in a project:

find_package(Intl)
target_link_libraries(app PRIVATE Intl::Intl)
