cmake_example | Example pybind11 module built with a CMake-based build | Build Tool library

I am wondering how to use pip to develop a Python package which is going through many revisions rapidly. My work flow is to write C++ code, compile and install with pip install and test my code.

Then, I would like to change some underlying C++ code, recompile and reinstall with pip, test the new feature, change something else, go back etc. until my package is ready.

Why did pip install ./cmake_example work well the first time but when making changes to the code, reinstalling with recompiling produced an error? I just re-ran the command pip install ./cmake_example.

I changed a single line of C++ code in an innocuous way (adding +1 in the 'add' function just to see if I can change code and recompile) and the code compiled fine in my IDE without pip.

My basic idea was to use pip following this method to avoid having to hackishly insert my shared object into some python directory each time I make a change.

I used the cmake_example from pybind here and followed the steps and did pip install ./cmake_example and it worked very well. I ran the example fine in a Python console.

Then, I changed some code (just added +1 to the adding function), so nothing substantial and wanted to re-install the package.

I then got this error:

I am wrapping some c++ library code to create a pybind11 module. I adopt the approach described here:

After building the library, it will be imported in Python using something like:

I'm having trouble understanding how to use pybind11 conan package. I can use some others, but pybind11 is giving me hard time.

My starting point is as follows:

conanfile.txt:

When I execute a command python setup.py install or python setup.py develop it would execute build_ext command as one of the steps. How can I pass --debug option to it as if it was invoked as python setup.py build_ext --debug?

UPDATE Here is a setup.py very similar to mine: https://github.com/pybind/cmake_example/blob/11a644072b12ad78352b6e6649db9dfe7f406676/setup.py#L43

I'd like to invoke python setup.py install but turn debug property in build_ext class instance to 1.

I'm trying a fairly simple experiment using cpack. The aim is to create an RPM installer (using cpack) with a trivial executable which uses an external 3rd party shared library (called libSomeSharedLib.so).

The structure I'd like the RPM to install is
