# CMAKE CODING STANDARD FOR PX4 |
|
# |
|
# Structure |
|
# --------------------------------------------------------------------------- |
|
# |
|
# * Common functions should be included in px_utils.cmake. |
|
# |
|
# * OS/ board specific fucntions should be include in |
|
# px_${OS}_utils.cmake or px4_${OS}_${BOARD}_utils.cmake. |
|
# |
|
# Formatting |
|
# --------------------------------------------------------------------------- |
|
# |
|
# * Use hard indents to match the px4 source code. |
|
# |
|
# * All function and script arguments are upper case. |
|
# |
|
# * All local variables are lower case. |
|
# |
|
# * All cmake functions are lowercase. |
|
# |
|
# Functions/Macros |
|
# --------------------------------------------------------------------------- |
|
# |
|
# * Use px4_parse_function_args to parse functions and check for required |
|
# arguments. |
|
# |
|
# * Never use macros. They allow overwriting global variables and this |
|
# makes variable declarations hard to locate. |
|
# |
|
# * If a target from add_custom_* is set in a function, explicitly pass it |
|
# as an output argument so that the target name is clear to the user. |
|
# |
|
# * Avoid use of global variables in functions. Functions in a nested |
|
# scope may use global variables, but this makes it difficult to |
|
# resuse functions. |
|
# |
|
# Included CMake Files |
|
# --------------------------------------------------------------------------- |
|
# |
|
# * Never set global variables in an included cmake file, |
|
# you may only define functions. This excludes Toolchain files. This |
|
# makes it clear to the user when variables are being set or targets |
|
# are being created. |
|
# |
|
# * All toolchain files should be included in the cmake |
|
# directory and named Toolchain-"name".cmake. |
|
# |
|
# Misc |
|
# --------------------------------------------------------------------------- |
|
# |
|
# * If referencing a string variable, don't put it in quotes. |
|
# Don't do "${OS}" STREQUAL "posix", |
|
# instead type ${OS} STREQUAL "posix". This will throw an |
|
# error when ${OS} is not defined instead of silently |
|
# evaluating to false. |
