## New override of `find_program('meson')` In some cases, it has been useful for build scripts to access the Meson command used to invoke the build script. This has led to various ad-hoc solutions that can be very brittle and project-specific. ```meson meson_prog = find_program('meson') ``` This call will supply the build script with an external program pointing at the invoked Meson. Because Meson also uses `find_program` for program lookups internally, this override will also be handled in cases similar to the following: ```meson custom_target( # ... command: [ 'meson', ], # ... ) run_command( 'meson', # ... ) run_target( 'tgt', command: [ 'meson', # ... ] ) ```
