Fix CMake error about source directory not existing

[bostick]

When I run the zlib tests, I get:

test 7
      Start  7: zlib_find_package_wrong_components_configure

7: Test command: /opt/homebrew/bin/cmake "-B/Users/brenton/development/github/tbt-parser/build/_deps/zlib-build/test/zlib_find_package_wrong_components_test_build" "-DCMAKE_BUILD_TYPE=" "-DCMAKE_C_COMPILER=/usr/bin/cc" "-DCMAKE_C_FLAGS=" "-DCMAKE_INSTALL_PREFIX=/Users/brenton/development/github/tbt-parser/build/_deps/zlib-build/test/test_install" "--fresh" "-G" "Unix Makefiles" "-S/Users/brenton/development/github/tbt-parser/build/_deps/zlib-build/test/zlib_find_package_wrong_components_test"

7: Specify --help for usage, or press the help button on the CMake GUI.
 7/36 Test  #7: zlib_find_package_wrong_components_configure ...   Passed    0.00 sec

Notice:

CMake Error: The source directory "/Users/brenton/development/github/tbt-parser/build/_deps/zlib-build/test/zlib_find_package_wrong_components_test" does not exist.

It looks like commit b2ed197 did not update everything in test/CMakeLists.txt.
