%description
The Point Cloud Library (PCL) is a standalone, large-scale, open-source C++
library for 2D/3D image and point cloud processing. It contains state-of-the-art
algorithms for filtering, feature estimation, surface reconstruction, model
fitting, registration, segmentation and visualization, used widely in robotics,
3D perception, LiDAR processing and computer vision.

# Eigen 5 trap: PCL requests Eigen3 3.3, which Fedora's eigen3 5.0.1
# (SameMajorVersion) rejects. Drop the version (PCL's own VERSION_LESS 3.3 guard
# still passes), and PCL 1.15.1 compiles cleanly against Eigen 5.

* Sat Jun 21 2026 Morgan Hough <morgan.hough@gmail.com> - 1.15.1-1
- Revive PCL (retired from Fedora at 1.12.0) at upstream 1.15.1. Builds against
  current Fedora: system Eigen 5.0.1 (drop the find_package 3.3 version pin),
  GCC 15, VTK, Qt5, Boost 1.90, FLANN, qhull. No CUDA/GPU; docs off. Provides the
  20 PCL libraries + headers/CMake config (-devel) + the pcl_* tools.
