FindJPEGXL
|
||||
---------
|
||||
Find JPEGXL headers and libraries.
|
||||
Imported Targets
|
||||
^^^^^^^^^^^^^^^^
|
||||
``JPEGXL::jxl``
|
||||
The JPEGXL library, if found.
|
||||
Result Variables
|
||||
^^^^^^^^^^^^^^^^
|
||||
This will define the following variables in your project:
|
||||
``JPEGXL_FOUND``
|
||||
true if (the requested version of) JPEGXL is available.
|
||||
``JPEGXL_VERSION``
|
||||
the version of JPEGXL.
|
||||
``JPEGXL_LIBRARIES``
|
||||
the libraries to link against to use JPEGXL.
|
||||
``JPEGXL_INCLUDE_DIRS``
|
||||
where to find the JPEGXL headers.
|
||||
``JPEGXL_COMPILE_OPTIONS``
|
||||
this should be passed to target_compile_options(), if the
|
||||
target is not used for linking

||||
