# 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
|
|
#
|
|
# 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
|
|
# subdirectories, 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.
|
|
#

|
# Warning: Changing this modifies CMake's internal workings
|
|
# and leads to wrong toolchain detection
