Extend target checks in cmake, in case it's run directly and not via idf.py or if idf.py misses something. This may happen for example if cmake variables are set in project's CMakeLists.txt. Some clean-ups are included along with the new checks and tests. 1. __target_check() function is removed. IIUC it should never fail, because the selected target is explicitly passed as environmental variable to kconfgen. Meaning the IDF_TARGET from environment variable may not be actually used in kconfgen if IDF_TARGET is already set it cmake cache. Note that the IDF_TARGET environment variable used for kconfgen is not based on the actual IDF_TARGET environment variable set for idf.py, but rather on the value set in __target_init() with set(IDF_TARGET ${env_idf_target} CACHE STRING "IDF Build Target") My understanding is that the original check was introduced to handle situation, where IDF_TARGET was already set in cmake's cache and the IDF_TARGET from environment variable was different. Since the kconfgen would use the original environment variable(not explicitly passed as it is now) the IDF_TARGET in cmake and in sdkconfig could differ. IOW I think the original check was introduced to cope with the following cmake behaviour set(VARIABLE "value1" CACHE STRING "test variable") set(VARIABLE "value2" CACHE STRING "test variable") message("Variable value: ${VARIABLE}") output: Variable value: value1 2. I scratched by head how it is possible that the following code in __target_check() if(NOT ${IDF_TARGET} STREQUAL ${env_idf_target}) could fail if IDF_TARGET is not set. For example in clean project IDF_TARGET=esp32 idf.py reconfigure Here env_idf_target==esp32 and IDF_TARGET is not set, so I would expect that cmake will fail with error message that the cache and env target do not match. The thing is that the variable evaluation is done before the if command, so it actually sees this if(NOT STREQUAL esp32) which is false and the error is not printed. It can be seen with 'cmake --trace-expand' command. I don't know if this was used on purpose or it worked just as a coincidence, but I find it very confusing, so I added explicit check if the IDF_TARGET is defined before the actual check. Same for CMAKE_TOOLCHAIN_FILE. 3. Error messages are not formated(line-wrapped) by cmake's markup so it's easier to check the output in tests.
