Could NOT find Boost (missing: python) on macOS - macos

Question

ERROR INF:
-- Could NOT find Boost (missing: python) (found version "1.71.0")
I've tried everything I found in here, and nothing works.
Here is what I've done:
Firstly, I've installed boost, boost_python and boost_python3 through brew install.
However, I noticed that in boost dir there are "include" and "lib" dirs, but there is only "lib" in boost_python and boost_python3, which I don't understand.
Run cmake as below:
CC=/usr/bin/gcc CXX=/usr/bin/g++ cmake
-DCMAKE_BUILD_TYPE="Release"
-DBUILD_QT5=1
-DCMAKE_PREFIX_PATH="/usr/local/Cellar/qt/5.13.1/lib/cmake"
-DFREECAD_USE_EXTERNAL_KDL=1
-DBUILD_FEM_NETGEN=1
-DFREECAD_CREATE_MAC_APP=1
-DCMAKE_INSTALL_PREFIX="./.."
-DPYTHON_LIBRARY=$ANACONDA_HOME/lib/libpython3.7.so
-DPYTHON_INCLUDE_DIR=$ANACONDA_HOME/include/python3.7
-DPYTHON_EXECUTABLE=$ANACONDA_HOME/bin/python3.7
-DBoost_NO_BOOST_CMAKE:BOOL=ON
-DBoost_NO_SYSTEM_PATHS=TRUE
-DBOOST_ROOT=/usr/local/Cellar/boost/1.71.0
-DBOOST_LIBRARY_DIRS=/usr/local/Cellar/boost/1.71.0/lib
-DBOOST_INCLUDE_DIR=/usr/local/Cellar/boost/1.71.0/include
../
But the log says:
Found Boost: /usr/local/Cellar/boost/1.71.0/include (found version "1.71.0")
Found PythonInterp: /bin/python3.7 (Required is at least version "3")

- Could NOT find Boost (missing: python) (found version "1.71.0")
As you can see, there are some components in Boost except for python.
I've tried:
-DBOOST_ROOT=/usr/local/Cellar/boost_python3/1.71.0_1
-DBOOST_LIBRARY_DIRS=/usr/local/Cellar/boost_python3/1.71.0_1/lib
But due to there's no "include" dir in boost_python3, I don't know how to edit BOOST_INCLUDE_DIR. Therefore, the log says:
Could NOT find Boost (missing: Boost_INCLUDE_DIR)
PLEASE HELP!!!!!!! I intend to compile FreeCAD on my mac but I've been stuck for a few days!
