I have been able to build Chromium from source, for Ubuntu using this guide.
Subsequently, I want to build the unit tests for it. And specifically, I want to build vaapi_unittest.
I have not been able to do so. First it failed on missing TTF fonts, but after adding a whole bunch of fonts to third_party/test_fonts/test_fonts/
I now get this failure: generate_fontconfig_caches failed with exit code 1
$ autoninja vaapi_unittest
[25/1011] CXX obj/ui/base/x/x/x11_util.o

generate_fontconfig_caches failed with exit code 1

ninja: build stopped: subcommand failed.
How can I avoid this error?
Or alternatively: I'm sure vaapi_unittest does not depend on fonts, so how can I prevent it from depending on that font and its font cache?
