Support recompiling on test run

[thejezzi]

Hi there,

would it be possible to execute a pre build step before a test run?
At the moment I always have to build my binary by hand and then use neotest, but it would make my life much easier if I could specify a prebuild task via the lets say ConfigureGtest command or a new ConfigureGtestBuild command or something, which could instead execute make or something similar and then the binary on every test run.

BTW: Thank you for this awesome plugin which makes my life already so much better :)

Hey @thejezzi
I was hoping to do this as part of CMake support (so by default this hook would try to find the relevant target through CMake), but that proved to be a bit more difficult than I thought (see this issue).

I suppose as an intermediate step I can add a user hook.

Would adding something like recompile = function(file_path, project_root) to config be good enough for the time being?

I don't think this plugin should depend on CMake.

Callback should be enough. Building can be done by a task plugin e.g. overseer.
Consider adding binary as a parameter, so it could be passed to the build system to speed up building (build only the binary containing test).

Another idea would be to use compile_commands and bypass the build system altogether. Although it's probably not very wise.
