我有一个生成静态库的CMake项目。它在QtCreator中编译得很好，并在build dir中生成库。静态库的CMakeLists.txt如下所示：

cmake_minimum_required(VERSION 3.5)

project(mystaticlib VERSION 0.1 LANGUAGES CXX)

set(CMAKE_CXX_STANDARD 20)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

file(GLOB mystaticlib_SRC "src/**.cpp")
add_library( mystaticlib STATIC
    ${mystaticlib_SRC}
)
target_include_directories( mystaticlib PRIVATE include/mystaticlib INTERFACE include )

现在我有了一个Qt应用程序项目，我想让它依赖于另一个项目，这意味着我可以在QtProject中做一些类似的事情：

cmake_minimum_required(VERSION 3.25)

project(MyQtProject VERSION 0.1 LANGUAGES CXX)

# This is how I imagine it working, not an actual code
include_project(mystaticlib, "~/my_projects/mystaticlib/CMakeLists.txt")
set(HEADERS_mystaticlib get_project_headers(mystaticlib))
# end of made up code
add_executable(MyQtProjectEXE ${PROJECT_SOURCES})
target_link_libraries(MyQtProjectEXE mystaticlib)
target_include_directories(MyQtProjectEXE HEADERS_mystaticlib)

我怎样才能得到这样的东西呢？在实践中，我希望它能工作，这样依赖的项目目录可以在cmake配置步骤中设置为任何东西。
