GoogleTest gtest_discover_test could not find test

Question

我正试图将谷歌测试添加到我的项目中，并不断获得

"[build]   get_property could not find TARGET testcolor.  Perhaps it has not yet been
"

这是我的cmake文件:

cmake_minimum_required(VERSION 3.13) 
project(RAYTRACE)             
set(CMAKE_CXX_STANDARD 20)           
include(FetchContent)
include(CTest)
enable_testing()#Redundent I know 
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${PROJECT_SOURCE_DIR}/lib)
set(INCLUDE_DIR ${PROJECT_SOURCE_DIR}/include)
include_directories("<...>/googletest-src/googletest/include")
##GTEST##
FetchContent_Declare(
googletest
GIT_REPOSITORY https://github.com/google/googletest.git
GIT_TAG release-1.12.1
)
set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
FetchContent_MakeAvailable(googletest)

set(SOURCE_FILES 
main.cpp
src/Utils/testcolor.cc
src/Utils/testcolor
)
add_executable(RAYTRACE ${SOURCE_FILES})
target_link_libraries(RAYTRACE
PRIVATE
testcolor
GTest::gtest_main
GTest::gtest
)
include(GoogleTest)
gtest_discover_tests(testcolor)

如果没有最后一行，则可以正确构建gtest，并且gtest.h头文件包含在"src/Utils/testcolor.cc"和发现。

但我不能添加测试。
