Boost/Py-Boost not being found in Conda Environment while Installing ParallelFDTD

I'm trying to follow the instructions here to install ParallelFDTD's python bindings on a windows machine. I've barely worked with C++ before, and certainly never with Boost! Mostly have experience with Python.
So far, I have done the following:
installed the Windows SDK
installed the CUDA toolkit
I have successfully created a conda environment:
conda create -n PFDTD -c conda-forge boost py-boost cmake numpy scipy
conda activate PFDTD
Running conda list shows that boost 1.73 is installed, along with py-boost 1.73 and libboost 1.73 as well as boost-cpp 1.68.
So far so good.
When I try to install and build the library as per the instructions with the following, I get an error
pip install git+https://github.com/AaltoRSE/ParallelFDTD.git
produces:

The key part of the error message seems to be:
Could NOT find Boost (missing: Boost_INCLUDE_DIR system thread date_time
unit_test_framework python38 chrono numpy38) (Required is at least version
"1.41")
The instructions suggest that the installation with conda should be sufficient, but it seems some environment variables are missing. In ParallelFDTD's CMakeLists.txt, you can see how it tries to handle boost installation in a conda env here.
It appears that conda install -c conda-forge boost py-boost installed successfully, for instance there are a lot of .hpp files and a /python folder as well as a bunch of other directories in C:\ProgramData\Anaconda3\envs\acoustics_env\library\include\boost. There are also a lot of boost_xxx.dll files in C:\ProgramData\Anaconda3\envs\acoustics_env\library\bin.
So far, I've forked the ParallelFDTD library so that I can make changes to the CMakeLists.txt, including pointing the BOOST_ROOT, Boost_INCLUDE_DIR and/or Boost_LIBRARY_DIR explicitly to folders in the anaconda env if need be, but I haven't been able to figure out the correct paths to use... I can also try installing boost manually, but just not sure what the best approach is.
Desperate for help! I'm sure it's a simple step I am missing...
Found lots of other threads that were somewhat related, but none of them seemed to be dealing with this kind of context of working in a conda environment with boost/py-boost.

Running CMAKE couldn't find python executable

Link for the issue raised in github: github issue link for reference
Application Version: CURA 3.6 version
Platform:
Processor: Intel(R) Core(TM) i5-8300H CPU # 2.30 GHz
RAM: 16.0 GB
System type: 64-bit Operating system, x64-based processor
Steps to Reproduce
I am trying to run source from https://github.com/Ultimaker/Cura/wiki/Running-Cura-from-Source-on-Windows#microsoft-visual-studio-2019.
And attempting to run step 10.
10:
Open CMake and point its source directory to your cura-build repository and the build directory to the build subdirectory.

Expected results
CMake should generate all files in build directory.
From the above error it is evident that the CMake is not able to find python executable.
I have no python installed on system. The only python available is from the CURA (which is installed when the cura-build-environment is build). How to link or make the CMake find the python executable which is installed?
For my case it is installed/found the executable in this folder:
\cura-build-environment-master\install_dir\bin

I have checked and found that we can set the python executable:
for windows:
set(Python3_EXECUTABLE D:/cura-build-environment-master/install_dir/bin/python.exe)

the same applies when building cgal-swig-bindings in the following way:

I hope someone knows what the problem is or suggestions which things to check?

I installed python with brew and followed this https://github.com/davisking/dlib/issues/889 and included this
>>>cmake -DCGAL_DIR=/usr/local/lib/cmake/CGAL -DBUILD_JAVA=OFF -DPYTHON_LIBRARIES=/usr/local/lib/python3.7 -DPYTHON_LIBRARY=/usr/local/Cellar/python/3.7.7/Frameworks/Python.framework/Versions/3.7/lib/libpython3.7.dylib -DPython_FRAMEWORKS=/usr/local/Cellar/python/3.7.7/Frameworks/Python.framework -DPYTHON_INCLUDE_DIR=/usr/local/Cellar/python/3.7.7/Frameworks/Python.framework/Headers
this worked for me!

buildroot opencv3 python package builds for the wrong target?

I am using buildroot tagged 2017.11.2 (building for aarch64). I enable build of python3 library for opencv3 in the buildroot configuration:
BR2_PACKAGE_PYTHON3=y
BR2_PACKAGE_OPENCV3=y
BR2_PACKAGE_OPENCV3_LIB_PYTHON=y
I can see during the build that cmake says:
-- Host: Linux 4.13.0-36-generic x86_64
-- Target: Linux aarch64
-- C++ Compiler: /home/buildroot/output/host/bin/aarch64-linux-gnu-g++ (ver 6.4.1)
But later I see
[100%] Linking CXX shared module ../../lib/python3/cv2.cpython-36m-x86_64-linux-gnu.so
[100%] Built target opencv_python3
I would expect cv2.cpython-36m-x86_64-linux-gnu.so to be named cv2.cpython-36m-aarch64-linux-gnu.so. What can I do to fix this?

It looks like the required distutils environment variables are not set. Can you try setting OPENCV3_CONF_ENV to $(PKG_PYTHON_DISTUTILS_ENV)? If that works, please prepare a patch and send it to the Buildroot mailing list.
