We are deliberately using a macro here instead of REQUIRED parameter because it is available only in CMake 3.18+, so it won't work with CMake version that is being shipped with RosBE. On my dev box the RosBE tools are only in the PATH when needed. Since my IDE inherits the PATH from the system and not from my shell, I needed to be able to run configure.sh with the tools in my PATH and then be able to successfully reconfigure when building from a "regular" command prompt.
