Marian Buschsieweke 6ac8aba955 build system: rework EXTERNAL_MODULE_DIRS ... Previously, external modules had to be individually added to both EXTERNAL_MODULE_DIRS and USEMODULE. If those where not in sync, this resulted in build errors. With this commit, search folders for external modules are added to EXTERNAL_MODULE_DIRS instead. So lets say the file system structure is like this ``` └── /path/to/external/modules    ├── mod_a    │   ├── Makefile    │   ├── Makefile.dep    │   ├── Makefile.include    │   ├── foo.c    │   └── include    │   └── external_module.h    └── mod_b   ├── Makefile    └── bar.c ``` One now adds `/path/to/external/modules` to EXTERNAL_MODULES and only with `USEMODULE += mod_a` the corresponding module, dependencies and include settings are actually used. Hence, it is possible to configure `EXTERNAL_MODULE_DIRS` from `~/.profile` or `~/.bashrc` once and never needs to worry about them again.		2021-05-07 21:29:05 +02:00
