      As was observed with building libmongoc during a C++ driver release with roberto.sanchez, it appears that libzstd may be detected and linked to with -lzstd, without the full path to the library being added.

      I observed this on macOS with cmake 1.16.2 when installing via the C++ driver's script:

      cd mongo-cxx-driver
./.evergreen/install_c_driver master
...

      cmake runs with:

      /Applications/Cmake.app/Contents/bin/cmake -DENABLE_AUTOMATIC_INIT_AND_CLEANUP=OFF -DENABLE_SHM_COUNTERS=OFF -DENABLE_BSON=ON -DENABLE_TESTS=OFF -DENABLE_EXAMPLES=OFF -DENABLE_STATIC=ON -DENABLE_EXTRA_ALIGNMENT=OFF -DCMAKE_MACOSX_RPATH=ON -DCMAKE_INSTALL_PREFIX=/Users/kevinalbertson/code/mongo-cxx-driver/../mongoc/ -DENABLE_CLIENT_SIDE_ENCRYPTION=OFF .

      And is able to find zstd:

      ...
-- Searching for compression library zstd
-- Checking for module 'libzstd'
--   Found libzstd, version 1.4.0
--   Found zstd version 1.4.0 in /usr/local/include
...

      But linking fails:

      ld: library not found for -lzstd
clang: error: linker command failed with exit code 1 (use -v to see invocation)
