See https://github.com/robotology/robotology-superbuild/actions/runs/1383461585 .

As we do not have any failure in normal CI, my guess is some dependency required for Planners/Bindings that is installed for the robotology-superbuild as an whole, but is not listed as a blf dependency in

robotology-superbuild/cmake/Buildbipedal-locomotion-framework.cmake

Line 63 in b1fa7c7

list(APPEND bipedal-locomotion-framework_CONDA_DEPENDENCIES spdlog)

. Note that qhull/cppad and all other dependencies that are part of the superbuild should already be covered as the fact that they are a conda-forge-provided dependency is encoded via the <pkg_name>_CONDA_PKG_CONDA_FORGE_OVERRIDE CMake option, see

robotology-superbuild/cmake/BuildCppAD.cmake

Line 15 in 545ec06

set(CppAD_CONDA_PKG_CONDA_FORGE_OVERRIDE ON)

Actually the planners component seems to be built.
