cmake export static lib and hide 3rd party libs

I am creating a static library lets call it X. This library uses rapidjson library in .cpp files. When I export this as static library, I want to hide rapidjson dependency. Another project should be able to link with

target_link_librares(another_project PUBLIC X)

My CMake configuration:

add_library(X STATIC
    hub.cpp
)

target_include_directories(X PUBLIC
    $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/..>
    $<INSTALL_INTERFACE:include>
)

get_target_property(X_INCLUDE_DIRS X INTERFACE_INCLUDE_DIRECTORIES)

target_link_libraries(X
    PUBLIC
    Y // this can be visible
    PRIVATE
    rapidjson // this should not required when another project links to X
)

install(TARGETS X
    EXPORT X-targets
    ARCHIVE DESTINATION lib
)

install(DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}/
    DESTINATION include/X
    FILES_MATCHING PATTERN "*.h" 
)

install(EXPORT X-targets
    FILE X-config.cmake
    NAMESPACE X::
    DESTINATION lib/X
)

When I install this and link to X, it requires for the line. However, this rapidjson is only used in the C++ files. And I want to hide this from end user.

find_package(RapidJson REQUIRED)

Is it possible to statically bundle these RapidJSON functions inside the X static library?
