FindSWIG
Find the Simplified Wrapper and Interface Generator (SWIG) executable.
This module finds an installed SWIG and determines its version. If a COMPONENTS
or OPTIONAL_COMPONENTS
argument is given to find_package
, it will also determine supported target languages. The module sents the following variables:
-
SWIG_FOUND
-
Whether SWIG and any required components were found on the system.
-
SWIG_EXECUTABLE
-
Path to the SWIG executable.
-
SWIG_DIR
-
Path to the installed SWIG
Lib
directory (result ofswig -swiglib
). -
SWIG_VERSION
-
SWIG executable version (result of
swig -version
). -
SWIG_<lang>_FOUND
-
If
COMPONENTS
orOPTIONAL_COMPONENTS
are requested, each available target language<lang>
(lowercase) will be set to TRUE.
Any COMPONENTS
given to find_package
should be the names of supported target languages as provided to the LANGUAGE argument of swig_add_library
, such as python
or perl5
. Language names must be lowercase.
All information is collected from the SWIG_EXECUTABLE
, so the version to be found can be changed from the command line by means of setting SWIG_EXECUTABLE
.
Example usage requiring SWIG 4.0 or higher and Python language support, with optional Fortran support:
find_package(SWIG 4.0 COMPONENTS python OPTIONAL_COMPONENTS fortran) if(SWIG_FOUND) message("SWIG found: ${SWIG_EXECUTABLE}") if(NOT SWIG_fortran_FOUND) message(WARNING "SWIG Fortran bindings cannot be generated") endif() endif()
