Yes, however you will need to change the library type to an `INTERFACE` library as documented in the [CMakeLists.txt](CMakeLists.txt). Yes, however you will need to change the library type to an `INTERFACE` library as documented in the [CMakeLists.txt](CMakeLists.txt).
- You are using `GLOB` to add source files in CMakeLists.txt. Isn't that evil? - I see you are using `GLOB` to add source files in CMakeLists.txt. Isn't that evil?
Glob is considered bad because changes to source files won't be automatically caught by CMakes builders and you will need remember to invoke CMake on any changes.

I personally prefer the `GLOB` solution for its simplicity, but feel free to change it to explicitly listing sources. I personally prefer the `GLOB` solution for its simplicity, but feel free to change it to explicitly listing sources.

CPM should be mostly invisible for your library users as it's self-contained and dependency free. CPM.cmake should be invisible for your library users as it's a self-contained CMake Script.
If problems do arise, they can always opt-out by defining `CPM_USE_LOCAL_PACKAGES`, which will override all calls to `CPMAddPackage` with `find_package`. If problems do arise, they can always opt-out by defining `CPM_USE_LOCAL_PACKAGES`, which will override all calls to `CPMAddPackage` with `find_package`.
If you are using `CPMFindPackage` instead of `CPMAddPackage`, CPM will always try to use `find_package` to add packages. If you concerned about this, you should prefer using `CPMFindPackage` instead of `CPMAddPackage`, as then CPM will try to use `find_package` to add packages whenever possible.
This approach should be compatible with any common C++ package manager without any user intervention, however at the cost of reproducible builds. `CPMFindPackage` approach should also be compatible with any common C++ package manager without modifications, however at the cost of reproducible builds.
