# Swiss Ephemeris Multi-platform Build Makefile
#
# This Makefile builds the Swiss Ephemeris project on both Linux and macOS.
#
# Features:
#  - Automatically detects the operating system using `uname`
#  - Sets appropriate compiler flags, library linking options, and shared
#    library creation flags for Linux and macOS.
#  - Builds dynamically linked executables (swetest, swevents, swemini) on both
#    platforms.
#  - Builds a fully statically linked executable (swetests) on Linux only.
#  - Creates both static (libswe.a) and shared libraries (libswe.so on Linux,
#    libswe.dylib on macOS) from the source object files.
#
# Targets:
#    all         - Build all executables (swetest, swevents, swemini, and swetests on Linux)
#    swetest     - Build the swetest executable using libswe.a (dynamic linking)
#    swetests    - Build a fully statically linked swetest (Linux only)
#    swevents    - Build the swevents executable
#    swemini     - Build the swemini executable using libswe.a (static linking)
#    libswe.a    - Create the static library archive from object files
#    libswe.$(DYLIB_EXT)
#                - Create the shared library (extension depends on OS)
#    test        - Run tests from the setest directory (requires a Makefile in setest)
#    clean       - Remove all generated files and clean the setest directory
#
# To customize, modify the CFLAGS, LIBS, or any other variables as needed.
