Unless search directories or overrides are provided, `find_program()` will by first search for an executable name in the source directory before trying to look it up via the `PATH` environment variable. This can create issues in some projects where the executable exists in the source directory, but when the actual program should be looked up via PATH. While the obvious answer is to move out the given executable from the source directory it's not always feasible. Git for example supports being built with both Makefiles and Meson. In the former case, the resulting `git` executable will be put into the root level source directory. So if one then sets up Meson, we would find that binary instead of the system-provided binary. Add a new "skip_source_dir" kwarg to `find_program()` that allows the user to skip looking up programs via the source directory. Signed-off-by: Patrick Steinhardt <ps@pks.im>
