[Native] Cleanup Cryptotools/CMakeLists.txt
Summary:
When adding the the CMakeLists.txt, I wasn't able to
reference the other sibling projects. This change is to remove
the target_include_directories entries in favor
of using target_link_library which is the more canonical way
to reference other projects now that they exist.
Test Plan:
nix develop cd native/cpp/CommonCpp rm -rf build && mkdir build && cd build && cmake .. && make -j
