Generated files shall be always placed in build directory.

AC:

• Header template file.h.in is created:

    /* @FILE_H@ -- Compatibility layer shim
        part of the minizip-ng project
        This program is distributed under the terms of the same license as zlib.
        See the accompanying LICENSE file for the full text of the license.
    */
    #ifndef @MZ_COMPAT_FILE@
    #define @MZ_COMPAT_FILE@

    #include "mz_compat.h"
    #endif

• CMakeLists.txt is updated:

    if(MZ_COMPAT)
        set(FILE_H "zip.h")
        set(MZ_COMPAT_FILE "MZ_COMPAT_ZIP")
        configure(file.h.in zip.h)

        set(FILE_H "unzip.h")
        set(MZ_COMPAT_FILE "MZ_COMPAT_UNZIP")
        configure(file.h.in unzip.h)

        if(MZ_COMPAT_VERSION)
            list(APPEND MINIZIP_DEF -DMZ_COMPAT_VERSION=${MZ_COMPAT_VERSION})
        endif()
        list(APPEND MINIZIP_SRC mz_compat.c)
        list(APPEND MINIZIP_HDR mz_compat.h ${CMAKE_CURRENT_BINARY_DIR}/zip.h ${CMAKE_CURRENT_BINARY_DIR}/unzip.h)
    endif()

Thanks for the good report. I have incorporated it into the dev branch.

You have forgot to add build directory to include_directories for target:
example target_include_directories(minizip PUBLIC ${minizip_BUILD_DIR})
Now unzip.h and zip.h cannot by found by other source.
I couldn't test it before

Ok please test dev.
