URGENT: Build System Hotfix

NOTE: Slated to be addressed in the rest of the repositories by T1303: Hotfix: Change `$<CONFIG>` to `${CMAKE_BUILD_TYPE}`.

@imirzali and I found an error in all CMakeLists.txt, which for reasons unknown worked until the latest version of CMake. Honestly, it shouldn't have ever worked. This, lads, is what we call a Schroedinbug.

IMPORTANT: Change every instance of $<CONFIG> to ${CMAKE_BUILD_TYPE} in both of the CMakeLists.txt files in your repository.

Thank you!
