[features] ImportError: DLL load failed with pybind11 and PCL

I'm using pybind11 to create a Python wrapper for a small C++ class.
I'm getting the following error when importing the DLL (running python -v to show Traceback):

>>> from a_py import *
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<frozen importlib._bootstrap>", line 991, in _find_and_load
  File "<frozen importlib._bootstrap>", line 975, in _find_and_load_unlocked
  File "<frozen importlib._bootstrap>", line 657, in _load_unlocked
  File "<frozen importlib._bootstrap>", line 556, in module_from_spec
  File "<frozen importlib._bootstrap_external>", line 1101, in create_module
  File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed
ImportError: DLL load failed while importing a_py: The specified module could not be found.

The class has just two members - types from the PCL library:

class A
{
   pcl::NormalEstimation< pcl::PointXYZ, pcl::Normal> normalEstimation_;
   pcl::PointCloud<pcl::Normal>::Ptr normals_;
};

If I remove the first member I can successfully import the module from the DLL.

This is the pybind11 code:

namespace py = pybind11;

PYBIND11_MODULE(a_py, m)
{
   py::class_<A>(m, "A");
}

PCL is found using CMake: find_package(PCL REQUIRED)

This happens on both Windows and Linux with the latest PCL (1.10) and older versions too.

(Adding #define PCL_NO_PRECOMPILE before the #includes does not help.)

Your Environment (please complete the following information):

• OS: Windows 10 (but similar issues on Linux)
• Compiler: MSVC 2019
• PCL Version1.10.0

Possible Solution

Based on a SO suggestion I ran the Dependencies app on both DLLs (with and without the offending line).
The main difference was that the offending DLL depends on c:\Program Files\PCL 1.10.0\bin\pcl_common.dll. Strangely enough, it seems to only rely on one function: void __cdecl pcl::console::print(enum pcl::console::VERBOSITY_LEVEL,char const * __ptr64,...).
AFAICT, PCL is mostly header only, and somewhere within the guts of pcl::NormalEstimation there is a logging function which is not header-only and needs linking. Is there a way to prevent this call?

BTW, the DLL is in the DLL paths (and as can be seen in the screenshot - available) so it is still unclear why Python fails to load the module.

Additional context

Add any other context about the problem here.

Start with the C++ class A and the pybind11 module a_py, comparing imports with and without pcl::NormalEstimation. Review the CMake find_package(PCL REQUIRED) setup and inspect the generated DLL dependencies, especially pcl_common.dll, using the Dependencies app. Done means the module imports successfully on the reported Windows and Linux setups without the missing-DLL error.
