# Configurable options:
#   CC       C compiler; GCC or Clang are fine; MSVC (2015+) works too.
#   CFLAGS   Compilation flags:
#             * Optimization level -O2 or higher is recommended
#            See config.h for some possible configuration macros.
#   LD       Linker; normally the same command as the compiler.
#   LDFLAGS  Linker options, not counting the extra libs.
#   LIBS     Extra libraries for linking:
#             * If using the native FPU, test_falcon and application
#               code that calls this library may need: -lm
#               (normally not needed on x86, both 32-bit and 64-bit)
