CMake Error

[RedactedProfile]

Following the installation instructions of

add_subdirectory(
        vendor/elzip
)
target_link_libraries(docproc2 PRIVATE
        elzip
)

results in this outcome:

-- Fetching zlib https://github.com/madler/zlib master
CMake Error at vendor/elzip/extlibs/minizip/CMakeLists.txt:197 (add_subdirectory):
  The binary directory

    /home/kharrison/source/docproc-v2/cmake-build-debug/_deps/zlib-build

  is already used to build a source directory.  It cannot be used to build
  source directory

    /home/kharrison/source/docproc-v2/cmake-build-debug/_deps/zlib-src

  Specify a unique binary directory name.

I understand this is more to do with minizip at that point, but what does one advise to do when encountering this situation while installing this library?

[Sygmei]

Oh, interesting problem

Do you include zlib in your main project directly ?
Do you happen to know why it doesn't trigger this condition ?

I have a similar cmake error:
