#
# Basic build targets:
#   all		all main tools and the shared library
#   static      build static binaries, requires static version of the libraries
#   test        run the full testsuite
#   install     install to default location (/usr/local)
#   clean       clean built binaries (not the documentation)
#   clean-all   clean as above, clean docs and generated files
#
# Tuning by variables (environment or make arguments):
#   V=1            verbose, print command lines (default: quiet)
#   C=1            run checker before compilation (default checker: sparse)
#   D=1            debugging build, turn off optimizations
#   D=dflags       dtto, turn on additional debugging features:
#                  verbose - print file:line along with error/warning messages
#                  trace   - print trace before the error/warning messages
#                  abort   - call abort() on first error (dumps core)
#                  all     - shortcut for all of the above
#                  asan    - enable address sanitizer compiler feature
#                  tsan    - enable thread sanitizer compiler feature
#                  ubsan   - undefined behaviour sanitizer compiler feature
#                  bcheck  - extended build checks
#   W=123          build with warnings (default: off)
#   DEBUG_CFLAGS   additional compiler flags for debugging build
#   EXTRA_CFLAGS   additional compiler flags
#   EXTRA_LDFLAGS  additional linker flags
#
# Testing-specific options (see also tests/README.md):
#   TEST=GLOB      run test(s) from directories matching GLOB
#   TEST_LOG=tty   print name of a command run via the execution helpers
#   TEST_LOG=dump  dump testing log file when a test fails
#
# Static checkers:
#   CHECKER        static checker binary to be called (default: sparse)
#   CHECKER_FLAGS  flags to pass to CHECKER, can override CFLAGS
#

# Export all variables to sub-makes by default
