Julia binding is not available for 4.5.4

##### System information (version)



- OpenCV => 4.5.4 ( both opencv/opencv_contrib )

- Operating System / Platform => Ubuntu 21.10

- Compiler => clang++-13



##### Detailed description

I try to use Julia binding in ubuntu 21.10. 

Julia library is found, but Julia binding is not available for 4.5.4. 

I think HAVE_JULIA flag handling should be checked.



cmake Log is below.



```

-- Could NOT find HDF5 (missing: HDF5_LIBRARIES HDF5_INCLUDE_DIRS) (found version "")

-- Registering hook 'STATUS_DUMP_EXTRA': /home/kmtr/work/opencv_contrib-4.5.4/modules/julia/cmake/hooks/STATUS_DUMP_EXTRA.cmake

-- Found Julia executable: /usr/bin/julia

-- Julia_VERSION_STRING: 1.5.3

-- Julia_INCLUDE_DIRS:   /usr/include/julia

-- Julia_LIBRARY_DIR:    /usr/lib/x86_64-linux-gnu

-- Julia_LIBRARY:        /usr/lib/x86_64-linux-gnu/libjulia.so.1

-- JULIA_HOME:           /usr/bin

-- Julia_LLVM_VERSION:   v9.0.1

-- Julia_WORD_SIZE:      64

-- Julia not found. Not compiling Julia Bindings. ON

-- Module opencv_ovis disabled because OGRE3D was not found

```



`-- Julia not found. Not compiling Julia Bindings. ON`



This message is shown in opencv_contrib-4.5.4/modules/julia/CMakeLists.txt

It means that HAVE_JULIA is not "YES", but is "ON"



```cmake

if(NOT HAVE_JULIA MATCHES "YES")

    message(STATUS "Julia not found. Not compiling Julia Bindings. ${HAVE_JULIA}")

```



"HAVE_JULIA" is set in opencv_contrib-4.5.4/modules/julia/cmake/init.cmake



```cmake

# --- Julia ---

if(WITH_JULIA AND NOT DEFINED Julia_FOUND)

  include(${CMAKE_CURRENT_LIST_DIR}/FindJulia.cmake)

  if(NOT Julia_FOUND)

    message(WARNING "Julia was not found. Disabling Julia bindings...")

    ocv_module_disable(julia)

  endif()



  set(HAVE_JULIA ON)

endif()

```



I grep "HAVE_JULIA". it seems to be better to use  "YES". 



```

kmtr@kmtr-virtual-machine:~/work$ grep HAVE_JULIA  opencv_contrib-4.5.4/ -r

opencv_contrib-4.5.4/modules/julia/CMakeLists.txt:if(NOT HAVE_JULIA MATCHES "YES")

```



There are same code in 4.x/5.x/master/next branches. 



##### Steps to reproduce



1. (I refer https://docs.opencv.org/4.x/d8/da4/tutorial_julia.html)

2. `sudo apt install julia julia-dev`

3. Download opencv-4.5.4 and opencv_contrib-4.5.4, and expand .

4. Execute cmake with this option.



```

cmake -S opencv-4.5.4 -B build -DCMAKE_CXX_COMPILER=clang++-13 -DOPENCV_EXTRA_MODULES_PATH=./opencv_contrib-4.5.4/modules -DWITH_JULIA=ON

```



##### Issue submission checklist



 - [X] I report the issue, it's not a question

 - [X] I checked the problem with documentation, FAQ, open issues,

       answers.opencv.org, Stack Overflow, etc and have not found solution

 - [X] I updated to latest OpenCV version and the issue is still there

 - [X] There is reproducer code and related data files: videos, images, onnx, etc
