Minter library dependency

[abhinavsns]

Minter is currently installed via a workaround using CMake and make. Any other advanced build tool like ninja fails to compile. To maintain consistency, minter should be shipped as a dependency.

See: https://github.com/mosaic-group/openfpm_numerics/blob/219d647b64ab80996a2b9b234eeb703f80e72caa/CMakeLists.txt#L39

As minter is no longer supported, we decided that parts of minter used in level-set will be rewritten to support openfpm data structures to be included as a part of openfpm_numerics. The rest will be dropped completely, which will solve the issue.

Unfortunately, the link is broken
