Regression in original introduction in commit
198e532300.
Every meson file in the repository must have this variable set, to an
appropriate per-file value, in order to cater to the split buildsystem
design where the build files are stored in a subdirectory away from the
source code.
If ossfuzz is enabled, this file is processed and the missing value will
come from some other file instead, which may not be correct.
- Using default values, ossfuzz is enabled but no other subdirs are, other
than of course lib, which has a coincidentally identical value, and
everything works.
- If contrib is enabled, it will set the per-file variable to a value
that is *not* coincidentally the same as ossfuzz.
- If examples is enabled, it will set the per-file variable to a value
that is coincidentally the same as ossfuzz... and do so later than
contrib.
So, if contrib is enabled but examples is not, then the ossfuzz
directory fails to process correctly and the build aborts. Fix this by
explicitly adding the correct per-file variable.

Meson build system for lz4
Meson is a build system designed to optimize programmer productivity. It aims to do this by providing simple, out-of-the-box support for modern software development tools and practices, such as unit tests, coverage reports, Valgrind, CCache and the like.
This Meson build system is provided with no guarantee.
How to build
cd to this meson directory (build/meson)
meson setup --buildtype=release -Ddefault_library=shared -Dprograms=true builddir
cd builddir
ninja # to build
ninja install # to install
You might want to install it in staging directory:
DESTDIR=./staging ninja install
To configure build options, use:
meson configure
See man meson(1).
