Testing seems to be broken

[SLieve]

To reproduce:

$ mkdir build && cd build && cmake -DENABLE_ROARING_TESTS=ON .. && cmake --build . && ctest
-- The CXX compiler identification is Clang 14.0.0
-- The C compiler identification is Clang 14.0.0

-- No build type selected, default to Release
CMake Error at tools/cmake/FindCTargets.cmake:7 (CPMAddPackage):
  Unknown CMake command "CPMAddPackage".
Call Stack (most recent call first):

-- Configuring incomplete, errors occurred!

Without -DENABLE_ROARING_TESTS=ON:

$ mkdir build && cd build && cmake .. && cmake --build . && ctest
...
[100%] Built target roaring
Test project CRoaring/build
No tests were found!!!

You are correct. This is getting fixed at #531

It was accidental.
