#
############################################################################
#=============================================================================
# CMAKE CODING STANDARD FOR PX4
#
# Structure
# ---------------------------------------------------------------------------
#
# * Common functions should be included in px_base.cmake.
#
# * 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 (${var} STREQUAL "2") <-- another condition
# # do somthing
# else () <-- leave blank
# # do somthing
# endif () <-- leave blank
#
# Functions/Macros
# ---------------------------------------------------------------------------
#
# * Use px4_parse_function_args to parse functions and check for required
# arguments. Unless there is only one argument in the function and it is clear.
#
# * Never use macros. They allow overwriting global variables and this
# makes variable declarations hard to locate.
#
# * If a target from add_custom_* is set in a function, explicitly pass it
# as an output argument so that the target name is clear to the user.
#
# * Avoid use of global variables in functions. Functions in a nested
# scope may use global variables, but this makes it difficult to
# resuse functions.
#
# Included CMake Files
# ---------------------------------------------------------------------------
#
# * All variables in config files must have the prefix "config_".
#
# * Never set global variables in an included cmake file,
# you may only define functions. This excludes config and Toolchain files.
# This makes it clear to the user when variables are being set or targets
# are being created.
#
# * Setting a global variable in a CMakeLists.txt file is ok, because
# each CMakeLists.txt file has scope in the current directory and all
# subdirecties, so it is not truly global.
#
# * All toolchain files should be included in the cmake
# directory and named Toolchain-"name".cmake.
#
# Misc
# ---------------------------------------------------------------------------
#
# * If referencing a string variable, don't put it in quotes.
# Don't do "${OS}" STREQUAL "posix",
# instead type ${OS} STREQUAL "posix". This will throw an
# error when ${OS} is not defined instead of silently
# evaluating to false.
