Update Pace-python build system

[a-larkins99]

New features:

• Add ability to use existing Horace/SpinW rather than downloading;
• Check included to test provided Horace/SpinW path;
• Add option to exclude Horace/SpinW from build;
• Add option to set version/release to download;
• Version checking for both Horace and SpinW included;
• Inclusion of libpymcr enabling use of previously incompatible Matlab and Python versions.

Usage:

python setup.py bdist_wheel <options>

After this the wheel can be installed and is located in the dist directory within pace-python.

List of new options introduced:

• WITH_HORACE - Set Horace use ON/OFF
• WITH_SPINW - Set SpinW use ON/OFF
• HORACE_PATH - Provide a path to your version of Horace
• SPINW_PATH - Provide a path to your version of SpinW
• HORACE_VERSION - Set the Horace release version to download e.g. 3.6.3
• SPINW_VERSION - Set the SpinW version (git tag/branch/hash)
• SPINW_REPO - Set the repo to get SpinW from e.g. "mducle/spinw"

Example:

If we want to turn SpinW off and use a version of Horace already on your machine you can run the following:

python setup.py bdist_wheel -DWITH_SPINW=OFF -DHORACE_PATH="/path/to/your/systems/Horace"

System specific comments

Windows:

May need to manually provide a Matlab path using the -DMatlab_ROOT_DIR="/path/to/Matlab" option.

Linux:

• Brille test appears to cause the the run_test.py script to hang following the completion of all the tests. Not an issue when running tests manually but when running on the jenkins job this will need to be disabled.
• libpymcr appears to struggle to find Matlab on Linux only.

Looks good. CI jobs on Jenkins are not running because this is from fork and it cannot find the commits in the main repo.

Updated CI is a work in progress
