autowarefoundation/autoware 'CMake Warning' issue
--- stderr: polar_grid
CMake Warning (dev) at CMakeLists.txt:7 (find_package):
Ignoring EXACT since no version is requested.
This warning is for project developers. Use -Wno-dev to suppress it.
The above warning appears multiple times, how to solve this issue? Thank you so much for your help!

Hi Harvey,
The warning appears because the find_package command in the CMakeLists.txt file, uses the EXACT keyword without specifying a version number.
To fix this, either remove EXACT if you don’t need a specific version, or add the required version number. For example, use find_package(some_package REQUIRED) or, if you need a certain version, find_package(some_package 1.2.3 EXACT REQUIRED). To supress the warning, you can add -Wno-dev to your CMake command line.
Hope this helps!
