Target "PreBuildEvent" skipped, due to false condition; ('$(PreBuildEvent)'!='') was evaluated as (''!='').
Some of you, might see this message in every build output of AVR Studio 5.0. I mention some of you because this depends on the build output verbosity level set in Studio 5.0. This is neither a warning nor an error. This is just a diagnostic message displayed by studio build system, to notify that it tried to run pre build events of the project but there is no such configured, and it evaluated to false. This is the same for the post build event also.
Edited : Use the build verbosity level “Normal” to have enough information from build output. Also note that this won’t affect the output verbosity of the underlying tool chain.
