CMake Error at: xobjdetect/CMakeLists.txt:6 (add_subdirectory) - OpenCV 5.0.0-alpha

[rajhlinux]

Hello,

Trying to build OpenCV using CMake GUI.

Performed the following:

git clone https://github.com/opencv/opencv.git
cd opencv
git fetch --all --tags
git tag
git checkout 5.0.0-alpha
git log -1
git submodule update --init --recursive

I get an error for xobjdetect module during config build process.
Here is the tree for the xobjdetect module:

Configuring incomplete, errors occurred!

What could be issue?

Thanks.

Alright, seems like there was some error in OpenCV core and OpenCV contrib folders, for which there was some mismatch in version contents and wasn't properly downloaded.

So I properly downloaded both the git sources and now seem to get no errors.
Here is how I did so:

OpenCV Core:

git clone https://github.com/opencv/opencv.git
cd opencv
git fetch --all --tags
git tag
git checkout 5.0.0-alpha
git log -1
git submodule update --init --recursive

OpenCV Extra Modules:

git clone https://github.com/opencv/opencv_contrib.git
cd opencv_contrib
git fetch --all --tags
git tag
git checkout 5.0.0-alpha
git log -1
git submodule update --init --recursive

Continue on in building OpenCV with CMake, should now give no errors.

[rajhlinux]

Actually this did not solved the issue, seems like I get the issue back once I start enabling BUILD_opencv_world feature...

If I disable BUILD_opencv_world, OpenCV CMake properly produces a proper configuration operation.

[kfcalf]

Yes,when BUILD_opencv_world is checked，the error come out，but if disable BUILD_opencv_world ，there will be lots of dlls

(I’m sorry there are no test environment on my PC. )

It looks like 'CMAKE_CURRENT_SOURCE_DIR' should be added in LINE6 .

I can reproduce this problem in Ubuntu 24.11.

If only set ${CMAKE_CURRENT_SOURCE_DIR} on data, following error is shown.

CMake Error at /home/kmtr/work/opencv_contrib5/modules/xobjdetect/CMakeLists.txt:6 (add_subdirectory):
  add_subdirectory not given a binary directory but the given source
  directory "/home/kmtr/work/opencv_contrib5/modules/xobjdetect/data" is not
  a subdirectory of "/home/kmtr/work/opencv5/modules/world".  When specifying
  an out-of-tree source a binary directory must be explicitly specified.
Call Stack (most recent call first):
  modules/world/CMakeLists.txt:13 (include)
  modules/world/CMakeLists.txt:50 (include_one_module)

So ${CMAKE_CURRENT_BINARY_DIR}/data is needed.

- add_subdirectory(data)
+ add_subdirectory(${CMAKE_CURRENT_SOURCE_DIR}/data ${CMAKE_CURRENT_BINARY_DIR}/data)

• cannops may have same problem. ( world -> cannops -> ascendc_kernel ) But I have no test environment.
• cudev is OK, because test is not included when world is enabled.
• julia and matlab may have same problem. ( world -> * -> test ).
• sfm seems be OK. ( world -> sfm -> libmv_light )
• xobjdetect-tools seems be OK. ( world -> xobjdetect -> tools -> waldboost_detector or annotation or visualisation )
• xobjdetect-data have this problem ( world -> xobjdetect -> data )

I was able to confirm that my patch works well. I have created a pull request.
If possible, I would appreciate it if you could try it on a Windows environment.
