问题：
AUTOGEN: No valid Qt version found for target opencv_opencl. AUTOMOC, AUTOUIC and AUTORCC disabled. Consider adding: find_package(Qt<QTVERSION> COMPONENTS Widgets) to your CMakeLists.txt file. This warning is for project developers. Use -Wno-dev to suppress it. CMake Error at AppNLP/CMakeLists.txt:255 (add_executable): Target "xxxxxxx" links to target "ZLIB::ZLIB" but the target was not found. Perhaps a find_package() call is missing for an IMPORTED target, or an ALIAS target is missing? Generating done CMake Warning: Manually-specified variables were not used by the project: QT_QMAKE_EXECUTABLE CMake Project parsing failed.
D:\AwsOneDriver\aStudioLk\AeolusPterosaurPlat\AppNLP\CMakeLists.txt:255: error: Target "appNLP_my" links to target "ZLIB::ZLIB"
but the target was not found. Perhaps a find_package() call is missing for an IMPORTED target, or an ALIAS target is missing?
:-1: error: Failed to compute build system.
当前的makefile写法：
find_package(ZLIB ) include_directories( "D:/win10/aspDep/zlib1211/x64/include") link_directories( "D:/win10/aspDep/zlib1211/x64/lib") ADD_DEFINITIONS (${ZLIB_DEFINITIONS})
问题的解决办法：
set( ZLIB_ROOT "D:/win10/aspDep/zlib1211/x64" ) find_package(ZLIB ) include_directories( "D:/win10/aspDep/zlib1211/x64/include") link_directories( "D:/win10/aspDep/zlib1211/x64/lib") ADD_DEFINITIONS (${ZLIB_DEFINITIONS})
是的，只需要加一行代码即可。
问题总结：
出现这个问题的原因不是由于protobuf库是否静态库，也不是由于zlib库是否静态库，而仅仅是因为没有找到zlib的根目录，由此导致找不到zlib的一些定义。

官网说明：https://cmake.org/cmake/help/latest/module/FindZLIB.html
Find the native ZLIB includes and library.
This module defines IMPORTED target ZLIB::ZLIB, if ZLIB has been found.
This module defines the following variables:
ZLIB_INCLUDE_DIRS - where to find zlib.h, etc.
ZLIB_LIBRARIES - List of libraries when using zlib.
ZLIB_FOUND - True if zlib found.
ZLIB_VERSION_STRING - The version of zlib found (x.y.z)
ZLIB_VERSION_MAJOR - The major version of zlib
ZLIB_VERSION_MINOR - The minor version of zlib
ZLIB_VERSION_PATCH - The patch version of zlib
ZLIB_VERSION_TWEAK - The tweak version of zlib
The following variable are provided for backward compatibility
ZLIB_MAJOR_VERSION - The major version of zlib
ZLIB_MINOR_VERSION - The minor version of zlib
ZLIB_PATCH_VERSION - The patch version of zlib
A user may set ZLIB_ROOT to a zlib installation root to tell this module where to look.
