Description

Since meson 0.40, meson it's able to install generated files into multiple directories. However, those installation directories are used one by one for each generated target.

It would be nice to have something like the following,

custom_target(
  output,
  input: output_input,
  output: output,
  command: cmd,
  install: true,
  install_dir: [dir1, dir2]
)

It would generate the output file after processing output_input file with the cmd command, and at install time, this file would be copied to dir1 and dir2.

Contributor guide

Research direction
Investigate the current implementation of custom target install dir in mesonbuild to understand how a single directory is handled, then extend it to support an array of directories.
