libcomps: Support builds with CMake 4+
Bump minimum required version to 3.10, the lowest one CMake 4+ don’t complain about. It’s also possible to use 3.5, but that results in a deprecation warning. The ‘cmake_minimum_required()’ invocation has been moved before the initial ‘project()’ call as CMake complained about the wrong order.
Set policy CMP0148 0 to OLD to unblock build without additional changes. Eventually, the usage of the ‘PythonInterp’ and ‘PythonLibs’ find modules will be need to be updated to use ‘Python3’ instead.
Set policy CMP0175 1 to NEW and fix warnings.
Fix the ‘No TARGET … has been created in this directory’ error in ‘src/python’.
Fix ‘Utility target
must not be used as the target of a target_link_libraries call’ errors (see 2). Mark the ‘check’ library as required when tests are enabled to prevent test targets from linking a non-existing library in case it’s not installed.
libcomps
Libcomps is alternative for yum.comps library. It’s written in pure C as library with Python bindings.

Building rpm package
You can use tito for building rpm package. From checkout dir:
Building Python package
To create a binary “wheel” distribution, use:
To create a source distribution, use:
Installing source distributions require the installer of the package to have all of the build dependencies installed on their system, since they compile the code during installation. Binary distributions are pre-compiled, but they are likely not portable between substantially different systems, e.g. Fedora and Ubuntu.
Note: if you are building a bdist or installing the sdist on a system with an older version of Pip, you may need to install the
scikit-build
Python package first.To install either of these packages, use:
To create an “editable” install of libcomps, use:
Note: To recompile the libraries and binaries, you muse re-run this command.
Installing
Testing
After build, you can find test for C library in tests directory, starting with
test_
prefix. Binding tests are at (for now) same directory as python binding library. You can runpython __test.py
orpython3 __test.py
(even without installing library) for tests bindings. Also this unittest serves as python bindings documentation (for now).Documentation
After build, documentation is in docs directory. Documentation is built in html xml and latex format. Only uncomplete documentation for C library is available at the moment. Look at bindings unittest
__test.py__
for python bindings usage.Contribution
