Let usdiscuss the steps necessary to achieve the packaging:

1. We extend account/CMakeLists.txt from Chapter 9, Mixed-language Projects, Recipe 6, Mixing C, C++, Fortran, and Python using Python CFFI. The only additions are the following directives:

file(
  GENERATE OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/interface_file_names.cfg
  INPUT ${CMAKE_CURRENT_SOURCE_DIR}/interface_file_names.cfg.in
  )

set_target_properties(account
  PROPERTIES
    PUBLIC_HEADER "account.h;${CMAKE_CURRENT_BINARY_DIR}/account_export.h"
    RESOURCE "${CMAKE_CURRENT_BINARY_DIR}/interface_file_names.cfg"
  )

install(
  TARGETS
    account
  LIBRARY
    DESTINATION account/lib
  RUNTIME
    DESTINATION account/lib
  PUBLIC_HEADER
    DESTINATION account/include
  RESOURCE
    DESTINATION account
  )

And that's it! With the install target and the additional files in place, we are ready to test the installation. For this, create a new directory somewhere on your computer and we will test the installation there.

2. Inside the newly created directory, we run pipenv install from a local path. Adjust the local path to point to the directory that holds the setup.py script:

$ pipenv install /path/to/fortran-example

3. Now we spawn a Python shell inside the Pipenv environment:

$ pipenv run python

4. Inside the Python shell, we can test our CMake package:

>>> import account
>>> account1 = account.new()
>>> account.deposit(account1, 100.0)
>>> account.deposit(account1, 100.0)
>>> account.withdraw(account1, 50.0)
>>> print(account.get_balance(account1))
150.0
