# Makefile to build and perform other useful operations on the Castle Game Engine.
#
# Requires using GNU make.
# - On Linux and most other Unixes, just call "make".
# - On FreeBSD call "gmake".
# - On Windows, install Cygwin ( http://www.cygwin.com/ ) with "make" package.
#   Make sure that when you type "make" it executes Cygwin's "make":
#   Cygwin's directory (like c:/cygwin64/bin/) should be on $PATH environment variable
#   *before* other directories with "make" implementations, like
#   - FPC directory that includes "make" from MinGW (it is GNU make but cannot execute bash scripts)
#   - Delphi directory that includes Embarcadero "make" (it's not GNU make and will fail).
#
# Most useful targets of this Makefile:
#
#   default (default target) --
#     Build the most useful things:
#     - tools not depending on LCL (including build tool)
#     - editor
#     Also, register all Lazarus packages.
#     Also, place all tools and editor in bin/ subdirectory.
#
#   tools --
#     Build all tools that don't depend on LCL.
#     Right now it means: all tools except castle-editor.
#
#   examples --
#     Compile most examples and tools (that don't use Lazarus LCL).
#     Lazarus is not required (LCL dependent examples are not compiled).
#
#     This compilation method calls our "build tool" to compile examples
#     and other tools (build tool, in turn, calls a compiler like FPC or Delphi).
#
#     The exception is when compiling the "build tool" itself,
#     then we call FPC directly. (Although we *could* use
#     the "build tool" to compile (bootstrap) itself, but it's not what
#     people expect by default, so we don't do it for now.)
#
#   examples-laz --
#     Compile all examples and tools using Lazarus (lazbuild).
#     This compilation method uses our .lpi project files,
#     and compiles every program by the lazbuild utility.
#     Lazarus and FPC installation is required.
#
#   build-using-fpmake:
#     Compile all units using FpMake.
#     We support this as an optional build approach to CGE and applications using CGE.
#     See https://castle-engine.io/fpmake .
#
#   clean --
#     Delete FPC temporary files, Delphi temporary files,
#     Lazarus temporary files (*.compiled),
#     binaries of example programs and tools.

# By default, use build tool compiled by tools/build-tool/castle-engine_compile.sh .
# This is easy, and when not cross-compiling, things will just work out-of-the-box,
# Makefile will always first build the build tool, then use it.
#
# You can override it on the command-line like "make BUILD_TOOL=castle-engine"
# to use build tool on $PATH .
# This is more reliable in some scenarios:
#
# - We will use build tool for current (source) system, even if CASTLE_FPC_OPTIONS
#   uses -T${OS} -P${CPU} to indicate a different (target) system,
#   so castle-engine_compile.sh doesn't build for current system.
#
# - Build tool can exist outside of CGE, and thus it exists regardless of "make clean" etc.
