Build: CMake compiler flags will be set, regardless of the cache status Defining CMake variables from the command-line or from another CMake project, such as `-DCMAKE_C_FLAGS= -DCMAKE_CXX_FLAGS=`, caused a link failure as ESP CMake was unable to set its proper compilation flags. Additional CMake compiler flags can now be provided by another project. * Closes https://github.com/espressif/esp-idf/issues/7507 2021-09-29 18:46:35 +08:00
