CMake definitions

The following definitions might be set by the user, depending on the needs.

definition	values	default	description
`AUTOSAR_STD_HEADER_PATH`	`-`	`CanTp/test/stub/common`	specifies the directory containing AUTOSAR standard headers ComStack_Types.h and Std_Types.h (used when integrating this module in an other project)
`CANTP_CONFIG_FILEPATH`	`-`	`CanTp/config/can_tp.json`	specifies which json configuration file should be used to generate the auto-generated code
`CANTP_ENABLE_TEST`	`ON`/`OFF`	`OFF`	enables/disables tests.
`ENABLE_DET`	`ON`/`OFF`	`ON`	enables/disables development error detections (see AUTOSAR DET module)
`ENABLE_DOC_GEN`	`ON`/`OFF`	`OFF`	enables/disables generation of Doxygen documentation
`ENABLE_PC_LINT`	`ON`/`OFF`	`OFF`	enables/disables generation of targets related to static code analysis (should be disabled if PC-Lint software is not available)
`MISRA_C_VERSION`	`1998`/`2004`/`2012`	`2012`	specifies which version of MISRA should be used when performing static code analysis (only used if `ENABLE_PC_LINT` is set)
`OS_GET_TIME_API`	`ON`/`OFF`	`OFF`	indicates whether the OSEK API GetElapsedValue is available or not. If enabled, the user is responsible to provide the function `uint32_t CanTp_GetElapsedValue(void)`

To use this feature, simply add -D<definition>=<value> when configuring the build with CMake.

Notes

Bellow, a few point to consider when using this module:

This module does not support nested interrupts. In other words, the functions CanTp_RxIndication, CanTp_TxConfirmation and CanTp_MainFunction (if scheduled using timer interrupt) should not be able to interrupt each other.

TODO

Protect variables used in both synchronous and asynchronous APIs.
