I have the exact same problem as stated in this question, but with a different configuration:

I am using OpenCV via VCPKG manifesto mode and the cmake is as follows:

cmake_minimum_required(VERSION 3.10)

File(TO_CMAKE_PATH $ENV{VCPKG_ROOT} VCPKG_ROOT)
message(STATUS ${VCPKG_ROOT})
set(CMAKE_TOOLCHAIN_FILE "${VCPKG_ROOT}/scripts/buildsystems/vcpkg.cmake" CACHE STRING "")
set(VCPKG_TARGET_TRIPLET "x64-windows-static-ffmpeg" CACHE STRING "")

project(test_project)


find_package(OpenCV REQUIRED)

set(INCLUDE_DIR "src/include")  # Change this if your library directory has a different path
include_directories(${INCLUDE_DIR})

# Set C++ standard to 20
set(CMAKE_CXX_STANDARD 20)

file(GLOB SRC_FILES "src/*.cpp" "src/*.c" )  # You can change "*.cpp" to "*.c" if your project uses C
file(GLOB INCLUDE_FILES  "${INCLUDE_DIR}/*.h" "${INCLUDE_DIR}/*.hpp") 

# Add an executable (replace "main.cpp" with your actual source file)
add_executable(test_program ${SRC_FILES} ${INCLUDE_FILES})
set_target_properties(test_program PROPERTIES
        MSVC_RUNTIME_LIBRARY "MultiThreaded$<$<CONFIG:Debug>:Debug>"
        )
# Include directories for header files
target_link_libraries(test_program ${OpenCV_LIBS})

and vcpkg is:

{
    "version": "1.0.0",
    "dependencies": [
        "opencv[core]"
    ]
}

and it is generating this error:

mismatch detected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value 'MDd_DynamicDebug' in main.obj  test_program opencv_core4d.lib(matrix.cpp.obj)      

I also tested this version of cmake and it did not worked:

cmake_minimum_required(VERSION 3.10)

File(TO_CMAKE_PATH $ENV{VCPKG_ROOT} VCPKG_ROOT)
message(STATUS ${VCPKG_ROOT})
set(CMAKE_TOOLCHAIN_FILE "${VCPKG_ROOT}/scripts/buildsystems/vcpkg.cmake" CACHE STRING "")
set(VCPKG_TARGET_TRIPLET "x64-windows-static-ffmpeg" CACHE STRING "")

project(test_project)


find_package(OpenCV REQUIRED)

set(INCLUDE_DIR "src/include")  # Change this if your library directory has a different path
include_directories(${INCLUDE_DIR})

# Set C++ standard to 20
set(CMAKE_CXX_STANDARD 20)

file(GLOB SRC_FILES "src/*.cpp" "src/*.c" )  # You can change "*.cpp" to "*.c" if your project uses C
file(GLOB INCLUDE_FILES  "${INCLUDE_DIR}/*.h" "${INCLUDE_DIR}/*.hpp") 

# Add an executable (replace "main.cpp" with your actual source file)
add_executable(test_program ${SRC_FILES} ${INCLUDE_FILES})
set_property(TARGET test_program PROPERTY
             MSVC_RUNTIME_LIBRARY "MultiThreaded$<$<CONFIG:Debug>:Debug>")
# Include directories for header files
target_link_libraries(test_program ${OpenCV_LIBS})

I delete the build directory on each run of make to ensure that nothing is cached and project generation is always started from scratch.

How can I fix this?
