Support for CMake

[AndreyAlifanov]

Normal support for using library clickhouse-cpp with CMake and vcpkg added. Also some errors fixed.

Current usage of library in projects requires writing many lines of code, sush as
find_library, find_package, include_directories, target_link_libraries for all dependencies.
It's very annoying and error prune.

find_library(CLICKHOUSE_CPP libclickhouse-cpp-lib.a REQUIRED)
find_package(zstd CONFIG REQUIRED)
find_package(lz4 CONFIG REQUIRED)
find_package(cityhash CONFIG REQUIRED)

target_link_libraries(${PROJECT_NAME}
  PRIVATE
    ${CLICKHOUSE_CPP}
    zstd::libzstd_static
    lz4::lz4
    cityhash
)

With my corrections all we need is:

find_package(clickhouse-cpp CONFIG REQUIRED)
target_link_libraries(${PROJECT_NAME} PRIVATE clickhouse-cpp-lib)

Hi @Enmk thank you for information. All CI jobs failed with the same errors. I'll investigate reasons.
