Install opencamlib into blender 2.93 on linux
Download portable version for linux64 2.83 or 2.93 from a command line as user to download and extract blender
$ cd ~/
$ mkdir Apps
$ cd Apps
$ wget https://ftp.nluug.nl/pub/graphics/blender/release/Blender2.93/blender-2.93.2-linux-x64.tar.xz
$ tar xf blender-2.93.2-linux-x64.tar.xz
$ cd blender-2.93.2-linux-x64/2.93/python/bin
$ ./python3.9 -m ensurepip
$ ./pip3 install shapely
$ ./pip3 install Equation
installing python and libboost-python headers
$ sudo apt install python3-dev libboost-python-dev
get the latest aewallin opencamlib sources
$ cd ~/Apps
$ git clone https://github.com/aewallin/opencamlib.git
$ cd opencamlib
$ mkdir build
$ cd build
$ cmake -DBUILD_PY_LIB=ON -DBUILD_CXX_LIB=ON -DUSE_PY_3=ON ..
$ make
this is optional
$ sudo make install
at this point opencamlib is compiled
if you ran make installthe terminal may show messages similar to this
[0/1] Install the project...

the python 3 version may depend on your system
now we need to link some files to the blender python3.9 interpreter
Depending on your base system python files may be in other place
from system if ran make install files should be here
/usr/lib/python3/dist-packages/ocl.so
or from opencamlib src dir
opencamlib/build/src/ocl.so
opencamlib/src/lib/STLTools.py
opencamlib/src/lib/procmemory.py
opencamlib/src/lib/camvtk.py
opencamlib/src/lib/pyocl.py

I got an python error, because print was used without () in the cmake file. I changed in the file ~/Apps/opencamlib/src/pythonlib/pythonlib.cmake in line 51 and 57 the python print command:
- old line 51 and 57
COMMAND ${PYTHON_EXECUTABLE} -c "from distutils.sysconfig import get_python_lib; print get_python_lib(0,0,\"/usr/local\")"
..
COMMAND ${PYTHON_EXECUTABLE} -c "from distutils.sysconfig import get_python_lib; print get_python_lib(plat_specific=1,standard_lib=0,prefix=\"/usr/local\")"
- new
