jasper?

[Framsfex]

This is on Ubuntu 24.04:

# cmake -H. -Btmp_cmake -DCMAKE_INSTALL_PREFIX=/sw/ubuntu-24.04/xv-3.10a-js-6.1.0
CMake version: 3.28.3
-- Could NOT find Jasper (missing: JASPER_LIBRARIES JASPER_INCLUDE_DIR)
JasPer library not found
CMake Warning at CMakeLists.txt:188 (message):
  Disabling JPEG-2000 Support.


CMake Warning at CMakeLists.txt:200 (message):
  Disabling EXIF Support.


-- Found the following WebP libraries:
--  WebP (required): /usr/lib/x86_64-linux-gnu/libwebp.so
JP2K: OFF
JPEG: ON
EXIF: OFF
TIFF: ON
PNG: ON
WEBP: ON
G3: ON
RANDR: ON
(...)

I have not found any thing about JasPer in the documentation.
Later I found https://github.com/jasper-software/jasper and installed it in /sw/ubuntu-24.04/jasper-4.2.8/
How do I integrate it with xv? How can I tell cmake to use it?
