CMake在Windows 10下使用GTest-致命错误LNK1104：无法打开文件'gtest.lib'，但是存在调试'gtestd.lib'

Question

我已经在这个问题上苦苦挣扎了一段时间：我在Windows 10下使用CMake和GTest，但得到了

(Link target) -> LINK : fatal error LNK1104: cannot open file 'gtest.lib' 

但是lib'gtestd.lib'的调试版本位于正确的文件夹中。我使用的是简单的文件夹结构：

test [folder]
 - CMakeLists.txt
 - test.cpp

[这意味着GTest会以某种方式在调试目标下进行编译（即使使用CMAKE_ARGS -DCMAKE_BUILD_TYPE = Release也无法强制执行），并且CMake会生成无法识别此GTest调试目标的VS灵魂，并尝试链接到版本'gtest。 lib”版本，不存在。

• 请帮助我，为此简单的方法编写正确的CMake文件测试并解决此问题。
• 也应该是正确的GTest目标，我相信是发布版本之一，因为我对此不感兴趣调试GTest库？

我的测试CMakeLists：

cmake_minimum_required(VERSION 2.8.12)

# Third-party library
include(ExternalProject)
ExternalProject_Add(googletest
    PREFIX "${CMAKE_BINARY_DIR}/lib"
    GIT_REPOSITORY "https://github.com/google/googletest.git"
    GIT_TAG "master"
    CMAKE_ARGS  -DCMAKE_INSTALL_PREFIX=${CMAKE_BINARY_DIR}/lib/installed
)

# Define ${CMAKE_INSTALL_...} variables
include(GNUInstallDirs)

# Specify where third-party libraries are located
link_directories(${CMAKE_BINARY_DIR}/lib/installed/${CMAKE_INSTALL_LIBDIR})
include_directories(${CMAKE_BINARY_DIR}/lib/installed/${CMAKE_INSTALL_INCLUDEDIR})

# This is required for googletest
find_package(Threads REQUIRED)

# target_sources 
# target_sources(cmake-sample2-main PUBLIC "../src/main.c")
set( SOURCES_TEST test.cpp )

# Test
add_executable(EmotionsModelLibraryTest ${SOURCES_TEST})
# Define the libraries this project depends upon
target_link_libraries(EmotionsModelLibraryTest libEmotionsModelLibrary gtest Threads::Threads)
# Make sure third-party is built before executable
add_dependencies(EmotionsModelLibraryTest googletest)

# has target scope—it adds x/y to the include path for target t.
# You want the former one if all of your targets use the include directories in question. You want the latter one if the path is specific to a target, or if you want finer control of the path's visibility. The latter comes from the fact that target_include_directories() supports the PRIVATE, PUBLIC, and INTERFACE qualifiers.
target_include_directories(EmotionsModelLibraryTest PRIVATE ${CMAKE_SOURCE_DIR}/include)

#possibly add to main after subdirectory
add_test(MyEmotionsModelLibraryTest EmotionsModelLibraryTest)

ps.s。如果我将链接器>附加依赖项手动设置为'gtestd.lib'，则它的构建没有问题。另外，在Ubuntu 18.04下，使用GTest的CMake可以完美工作]
