分析一下PX4代码CMakeLists.txt文件

#=============================================================================
# CMAKE CODING STANDARD FOR PX4
#
# Structure
# ---------------------------------------------------------------------------
#
# * Common functions should be included in <span style="color:#ff0000;">px_base.cmake.</span>
#
# * OS/ board specific fucntions should be include in
#	px_impl_${OS}.cmake or px4_impl_${OS}_${BOARD}.cmake.
#
# Formatting
# ---------------------------------------------------------------------------
#
# * Use hard indents to match the px4 source code.
#
# * All function and script arguments are upper case.
#
# * All local variables are lower case.
#
# * All cmake functions are lowercase.
#
# * For else, endif, endfunction, etc, never put the name of the statement
#
#	Instead of the very confusing:
#		if (${var} STREQUAL "1") <-- condition now becomes if name
#			# do somthing
#		elseif (${var} STREQUAL "2") <-- another condition
#			# do somthing
#		else (${var} STREQUAL "1") <-- tag is referring to name of if
#			# do somthing
#		endif (${var} STREQUAL "1") <-- tag is referring to name of if
#
#	Do this:
#		if (${var} STREQUAL "1") <-- condition now becomes if name
#			# do somthing
#		elseif (${var} STREQUAL "2") <-- another condition
#			# do somthing
#		else () <-- leave blank
#			# do somthing
#		endif () <-- leave blank
#
# Functions/Macros
# ---------------------------------------------------------------------------
#
# * Use px4_parse_function_args to parse functions and check for required
#   arguments. Unless there is only one argument in the function and it is clear.
#
# * Never use macros. They allow overwriting global variables and this
#	makes variable declarations hard to locate.
#
# * If a target from add_custom_* is set in a function, explicitly pass it
#	as an output argument so that the target name is clear to the user.
#
# * Avoid use of global variables in functions. Functions in a nested
#	scope may use global variables, but this makes it difficult to
#	resuse functions.
#
# Included CMake Files
# ---------------------------------------------------------------------------
#
# * All variables in config files must have the prefix "config_".
#
# * Never
