Support the Meson build system

[Andreas Stöckel]

Meson is a relatively new and popular build system with a simple declaration language, integrated dependency management, and good cross-compilation support. Supporting Meson in libvterm allows developers to easily integrate libvterm into their own Meson-based project.

The only change that had to be done in libvterm to support Meson is to add an additional "--executable" parameter to run-test.pl, so that the unit-tests can be executed within an out-of-tree build.

Here are my patches:

[PATCH] Add --executable/-e flag to run-test.p
https://github.com/astoeckel/libvterm/commit/0e7e03060b97e3a4a8269544b72b630ede82495c.patch

[PATCH] Add meson.build
https://github.com/astoeckel/libvterm/commit/27c1bfe1c655cbcaf550e589a176aced6c1a4bfc.patch

[PATCH] Ignore "build" directory in bzr
https://github.com/astoeckel/libvterm/commit/efe673b6e44f9974cdbbb5bfbbdc89027a1dfcc4.patch

[PATCH] Symlink .bzrignore to .gitignore
https://github.com/astoeckel/libvterm/commit/c424d6539db642f14e0ef3a7fae00e4e7689153d.patch

Note that only the first two patches are really required, the last two patches are more quality-of-life improvements for myself.

Patch (1/4) looks good; I've applied as bzr -r722

Patch (2/4) looks interesting - it hardcodes a full list of the test filenames. Is there not a way to glob the directory for all of them? That looks like it could be a problem to keep it maintained as more tests get added. Additionally, can you add a comment to the file giving some author information, so I can remember where to send questions to in case problems come up - since I didn't write that bit :)

[Andreas Stöckel (andreas-stoeckel)]

First of all, thank you for looking at this and sorry for the delay!

The rationale for the missing wildcard/globbing operator in Meson is documented here [1]. I have adapted the patch to use the workaround described in the Meson documentation, i.e. to use an external program to search for files. There is now a small Perl script "t/list-tests.pl" that lists all *.test files in the "t/" directory.

Here are the updated patches:

Forgot to add: I also added some author information to the new files.
