Description

I noticed that setting the with_openmp and with_opencv options for the pcl package through a conanfile.txt does not seem to have any effect. Even though I explicitly set:

[requires]
pcl/1.14.1

[options]
pcl/*:with_openmp=True
pcl/*:with_opencv=True

the resulting build of PCL behaves as if both options were still disabled. The CMake configure output shows that OpenMP and OpenCV support are not being enabled, and the compiled package confirms this.

I'll try to investigate the issue further when I have time—possibly something in the recipe's config_options, configure, or CMake integration path is overriding or ignoring the values passed from a conanfile.txt.
