| # This script deletes any -I command line arguments that are not | |
| # - Absolute paths. | |
| # - Ephemeral build directories. | |
| # | |
| # This function is necessary because Meson does not give adequate | |
| # control over what directories are passed in as -I search directories | |
| # to the C compiler. While Meson does provide |implicit_include_directories|, | |
| # support for this option is poor: empirically, Meson ignores this option for | |
| # some targerts. Doing it as a post-processing step ensures that Meson does | |
| # not allow improper #includes to compile successfully. | |
| # | |
| # This is run by meson as a postconf script. The following env variables will be | |
| # set: | |
| # - MESON_SOURCE_ROOT | |
| # - MESON_BUILD_ROOT | |
