* PKGBUILD:
- upgrade igraph version to 0.9.3
- remove references to obsolete patch (issue covered upstream)
- use cmake generator 'Ninja' instead of 'MSYS Makefiles' and use
cmake commands for build and install (instead of calling make)
- add cmake config -DIGRAPH_ENABLE_TLS=1
- remove cmake config -DIGRAPH_VERIFY_FINALLY_STACK=1 (devel only)
- build static and shared library separately, and install one over
another (where order is important to ensure to have the correct
header file 'igraph_export.h' working for both static and shared
linking).
- add generation of .pc files igraph-shared.pc and igraph-static.pc
- remove cmake files to avoid confusion when both shared and static
libraries are installed (implementation assumes that one of them only
is installed).
* 0001-igraph-0.9.0-link-libm-only-when-needed.patch:
- remove since obsolete after issue was resolved upstream.
NB: All tests succeeded for MINGW64 locally.
* PKGBUILD
- upgrade to 0.9.0

* 0001-igraph-0.9.0-link-libm-only-when-needed.patch
