merge pull request #960 from yosefm/numpy-distutils-byebye, closes #944
initial make files
File removed in master
Add another depenency of terms to CMakeLists
Don’t ignore cmake
Build file depending on another directory
Change installation target dir
Make install testable
Change order of commands to what’s apparently expected. See https://scikit-build.readthedocsa.io/en/latest/cmake-modules/PythonExtensions.html ‘Amend the configuration of the library target (created using add_library) … ‘
sfepy_common should be static Otherwise it’s not found on runtime. Also, no need to install it then.
More builds Should get us done with sfepy.discrete, but tests fail to import (but not from … import)
Get tems.extmods fully built So that sfepy.discrete can import
Install tests as data files so that tests actually run. some of them fail on not finding their meshes, but that’s for next commit.
Add meshes directory to install Maybe would be preferable to follow the setuptools current advice and move it into the package, but this branch is already shaking the boat pretty hard, so let’s leave it for a later PR.
Fix some missing links
Add mechanics/extmods first time all tests pass
Move common definitions to main CMake file
clean up a bit
Clean up early experiments
Compose compile flags as in numpy distutils
distutils only adds cflags for unices
Handle debug flags in site_cfg
Responsibility for link flags moves to CMake fully Until anyone demands it back. It would be better to do this through CMakeLists anyway.
Install examples too Leave wider pyproject.toml reform for later :)
Feature completion
Use setup_test.py as the new setup.py
Add skbuild to pyproject.toml
Remove 3.9 annotations
Steal distutils hack to install data with package.
Editable install not well-supported by skbuild
Fix: doesn’t write the version file.
Run coverage using installed package
Fix relative paths
Windows peculiariuty?
Removals
One more removal
Observe line length in an skbuild-acceptable way
disable C++ in CMake As it will not be found in the conda recipe and is not actually needed, since the conda recipe always specified onlt a C compiler.
Languages also inb setup.py
Use Ninja generator explicitly
Add new build dependencies also to docs
Keep support for space-separated flag strings
Manually include compiled files in manifest
replace global-include by recursive-include, exclude _skbuild
Catch manifest up with removed file in master
