<div dir="ltr"><div><div>Hi Rob, <br><br></div>Do address the use case you described, I usually explicitly set the path the library when built as an external project and rely only on the find_* command for the use_system case.<br>

<div>Rob</div><div><br></div><div><br></div><div>Background... Basically, I am using ExternalProject_Add to build a library. However, to make it possible to use the system-library instead, this is optional. I use a FindThelib.cmake so the main project works seamlessly either way.</div>
