I was getting this error on macOS: ``` ld: library 'c++' not found clang++: error: linker command failed with exit code 1 (use -v to see invocation) ``` Took a while to track down the issue, but it turned out this warning at the end of `cmake` was key: ``` CMake Warning at src/CMakeLists.txt:40 (target_link_libraries): Target "clickhouse_fdw" requests linking to directory "/Library/Developer/CommandLineTools/SDKs/MacOSX15.sdk". Targets may link only to libraries. CMake is dropping the item. ``` This is fine, except that that CMake doesn't remove the option this directory points to. The option is stored by `pg_config`; you can see it here: ``` console pg_config --ldflags -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX15.5.sdk -L/opt/homebrew/opt/readline/lib -Wl,-dead_strip_dylibs ``` What we need to do is remove both the macOS SDK and `-isysroot`. So add a section to `CMakeLists.txt` that uses `REGEX REPLACE` to remove the complete option from the output of `pg_config` on macOS.
