## Makefile variables
You may need `profiledir=$out/etc/profile.d` and `sysconfdir=$out/etc` to run
`make install`.
You may want to set `MAKEFLAGS="-e -j $NIX_BUILD_CORES"` to allow environment
variables to override `Makefile` variables.
- `ENABLE_BUILD=yes` to enable building the C++ code.
- `ENABLE_DOC_GEN=yes` to enable building the documentation (manual, man pages, etc.).
The docs can take a while to build, so you may want to disable this for local development.
- `ENABLE_FUNCTIONAL_TESTS=yes` to enable building the functional tests.
- `ENABLE_UNIT_TESTS=yes` to enable building the unit tests.
- `OPTIMIZE=1` to enable optimizations.
- `libraries=libutil programs=` to only build a specific library (this will
fail in the linking phase if you don't have the other libraries built, but is
useful for checking types).
- `libraries= programs=nix` to only build a specific program (this will not, in
general, work, because the programs need the libraries).
