Can link against custom targets

The output of custom_target and custom_target[i] can be used in link_with and link_whole keyword arguments. This is useful for integrating custom code generator steps, but note that there are many limitations:

• Meson can not know about link dependencies of the custom target. If the target requires further link libraries, you need to add them manually

• The user is responsible for ensuring that the code produced by different toolchains are compatible.

• custom_target may only be used when it has a single output file. Use custom_target[i] when dealing with multiple output files.

• The output file must have the correct file name extension.
