libopenjp2-7-dev has missing dependencies

[Momtchil Momtchev]

libopenjp2-7-dev installs a CMake module that references missing files making it impossible to use the package from CMake projects:

ERROR MESSAGE:

-- The imported target "openjpip" references the file
   "/usr/lib/x86_64-linux-gnu/libopenjpip.so.2.4.0"
but this file does not exist. Possible reasons include:
* The file was deleted, renamed, or moved to another location.
* An install or uninstall procedure did not complete successfully.
* The installation package was faulty and contained
   "/usr/lib/x86_64-linux-gnu/openjpeg-2.4/OpenJPEGTargets.cmake"
but not all the files it references.

The missing packages are:

libopenjp2-tools
libopenjpip-server
libopenjpip-viewer

Additionally, the included UseOPENJPEG.cmake is not meant to be used standalone, but it is meant to be included from a missing UseOPENJPEG.cmake file.

The first part is definitely an Ubuntu problem, but the second part might be the library authors problem:

[Momtchil Momtchev (mmomtchev)]

Starting with openjpeg 2.5.2 the CMake files are actually usable:
https://github.com/uclouvain/openjpeg/commit/5c2053950eb4c2c76f17deefd35f5c49abf0232e

(tho, not without any problems...)

Only the dependencies should be fixed in Ubuntu - the -dev package should install all the binary packages
