Implemented igraph

[carloscbl]

• Fixes python-igraph #539

It need to use ENV
IGRAPH_CMAKE_EXTRA_ARGS='-DF2C_EXTERNAL_ARITH_HEADER=/home/cbernal/Downloads/android64_x86_64_arm64.h -DIEEE754_DOUBLE_ENDIANNESS_MATCHES=ON'

During the execution of build-wheel.py

And needs to use api-level 24

IGRAPH_CMAKE_EXTRA_ARGS='-DF2C_EXTERNAL_ARITH_HEADER=/home/cbernal/Downloads/android64_x86_64_arm64.h -DIEEE754_DOUBLE_ENDIANNESS_MATCHES=ON' ./build-wheel.py -v --api-level 24 --python 3.11 --abi arm64-v8a igraph

If it helps generalize the PR, I believe the same arith.h is also appropriate for aarch64, not just for x86_64.

Thanks very much. To merge this PR, we'll need to fix F2C_EXTERNAL_ARITH_HEADER so it doesn't contain user-specific paths. Maybe this can be done by patching the package's build script to set the variable, rather than setting it in meta.yaml.

We'll also need a test script to verify that the package works. Please do the following:

• Follow the instructions in "Testing a package" in the README.
• Push your test script to this PR.
• Post a comment saying which Python versions and ABIs you have tested.

This was failing because of finding
IGRAPH_CMAKE_EXTRA_ARGS=-DF2C_EXTERNAL_ARITH_HEADER=../../../../../../../android64_x86_64_arm64.h -DIEEE754_DOUBLE_ENDIANNESS_MATCHES=ON

Multiple "=", now will only take the first segment as key and the rest as value as is

tested in Python 3.11, and ABIs:

def abiFilters_ = ["x86_64", "arm64-v8a"]
chaquopy {
    defaultConfig {
        version = "3.11"
        pip {
            options "--find-links", rootProject.projectDir.toString() + "/childmodule/wheels/igraph"
            install("igraph==0.11.5")
            install("numpy==1.26.2")
            install("requests==2.24.0")
            install("dateparser==1.2.0")
            install("Babel==2.10.3")
            install("python_dateutil==2.8.2")
            install("pytz==2024.1")
            install("langdetect==1.0.9")
            install("tzlocal==5.2")
            install("regex")
            install("coloredlogs")
            install("logging_json")
            install("tzdata")
            ...

project.ext {
        COMPILE_SDK_VERSION = 33
        MIN_SDK_VERSION = 26
        TARGET_SDK_VERSION = 33
        BUILD_TOOLS_VERSION = '33.0.0'

Tested on ubuntu with pixel 4 API 31 emulator x86_64
and
Tested on physical Samsung S22 ultra SM-S908B/DS exynos arm64

By tested i mean i have a script the uses all that packages, and is working

[szhorvat]

python-igraph 0.11.6 is out now, you could consider packaging that version instead.
