Description of issue

On my Apple M1Pro running Sequoia 15.2 after brew upgrade && brew reinstall visp I have:

% brew info visp
==> visp: stable 3.6.0 (bottled)
Visual Servoing Platform library
https://visp.inria.fr/

/opt/homebrew/Cellar/visp/3.6.0_10 (812 files, 11.8MB) *

that brings ViSP CMake material in /opt/homebrew/Cellar/visp/3.6.0_10/lib/cmake/visp (VISPConfig.cmake and VISPModules.cmake).

I have also:

Now when I try to build a simple project with
CMakeLists.txt file content:

cmake_minimum_required(VERSION 3.10)

project(test-brew-opencv)

find_package(VISP)
add_executable(test-opencv test-opencv.cpp)
target_include_directories(test-opencv PRIVATE ${VISP_INCLUDE_DIRS})
target_link_libraries(test-opencv ${VISP_LIBRARIES})

and test-opencv.cpp file content:

#include <visp3/core/vpImage.h>
#include <visp3/core/vpImageConvert.h>
#include <visp3/core/vpConvert.h>

int main()
{
  cv::Mat mat(3, 3, CV_8UC1, 10);
  vpImage<unsigned char> I;
  vpImageConvert::convert(mat, I);
  for (unsigned int i = 0; i < mat.rows * mat.cols; ++i) {
    if (I.bitmap[i] != 10) {
      std::cout << "Error in image conversion from opencv to visp" << std::endl;
      return EXIT_FAILURE;
    }
  }

  vpImagePoint ip(10, 20);
  cv::Point2d cv_point2d;
  vpConvert::convertToOpenCV(ip, cv_point2d);

  if ((ip.get_u() != cv_point2d.x) || (ip.get_v() != cv_point2d.y)) {
    std::cout << "Error in point2d conversion from visp to opencv" << std::endl;
    return EXIT_FAILURE;
  }

  std::cout << "Test succeed" << std::endl;
  return EXIT_SUCCESS;
}

I got the following build issues:

I found that in VISPConfig.cmake and VISPModules.cmake there are references to MacOSX14.sdk.

The fix I found is to replace in these 2 files MacOSX14.sdk by MacOSX15.sdk.

I don't know if this is something that comes from the way visp bottle is build or if this is related on how visp exports the 3rdparties in VISPConfig.cmake and VISPModules.cmake?

That'll be because we don't have a macOS 15 bottle for this yet: https://github.com/Homebrew/homebrew-core/blob/4cfcf247356632cec65981550ec479a5c379df1a/Formula/v/visp.rb#L15

Ideally it wouldn't make any reference to any SDK at all, but there are some that do anyway for one reason or another. Will need to dig deeper into where it comes from and see if we can remove it.
