Utilize CDeps.cmake

[threeal]

This issue suggests utilizing the CDeps.cmake module for installing missing dependencies in the project, replacing the CPM.cmake module.

CDeps is proposed for use because, compared to CPM, CDeps will build and install the project during the configuration time, with a scope separated from the main project. This will allow the find_package function to behave the same whether it finds the missing package on the system or not. This is different from CPM, which includes the missing package as a subdirectory and builds the target altogether, potentially cluttering the main project target with the targets from dependencies.
