Support OpenJPEG 2.5

[VVD]

Build failed with OpenJPEG 2.5.0 - there are no check for includes openjpeg-2.5/openjpeg.h.
Found list of files with check for OpenJPEG:
CMakeLists.txt
cmake/Configure.cmake
config/config.h.in

Will try to fix this and show patches in comments.

Build fine for me on FreeBSD 12.3 amd64 with patches below.

Maybe a better solution is using pkg-config to check whether OpenJPEG is available and to get the necessary compiler and linker flags. That would also work for a future OpenJPEG 2.6.

[zdenop]

pkg-config is not standard on all platform (e.g. Windows) ;-)
using find_package(OpenJPEG) should be better solution for cmake...

[stweil]

Builds with autoconf already use pkg-config and should work with OpenJPEG 2.5. And yes, for cmake builds find_package would be the best solution.

[VVD]

Don't think I can implement this in near future.
If you can please do it. And maybe next release just after this. :-]
Thanks!

[zdenop]

#624 should solve it. Please test it.

#624 should solve it. Please test it.

Thanks.
But I can't apply patch to last release version without errors. What list of commits it require?
I explore a bit and it's look like hard work to separate required commits.

The easiest option for me is to release a new version and I can test it.

[zdenop]

There is no need to patch anything - just download the recent code:

[VVD]

I know this possibility, but I build via FreeBSD ports.
To do this I must modify this port. It use releases and change it to use last version from git is not so fast and trivial work.

[VVD]

I "made release" 1.82.1 from git master:

cd /usr/ports/distfiles
wget https://github.com/DanBloomberg/leptonica/archive/refs/heads/master.zip
unzip master.zip
mv leptonica-master leptonica-1.82.1
tar -zcf leptonica-1.82.1.tar.gz leptonica-1.82.1
cd /usr/ports/graphics/leptonica
# fix version from 1.82.0 to 1.82.1 and remove extra patches from commits
vi Makefile
make makesum
make

Build without errors.

[VVD]

In 3 words: work for me. :-]

[VVD]

Waiting release.
