Examples CMake missing support of shared lib

[z-vishal]

hi

While building ZenDNN with a shared library and examples, I encountered an issue related to the examples build configuration. The examples build configuration only links the static library (zendnnl_archive) and doesn't handle the case of a shared library

Issue: current code hardcodes linking to static library only

Line: 87

ZenDNN/examples/CMakeLists.txt

Lines 85 to 87 in fc28bba

	target_link_libraries(examples
	PUBLIC OpenMP::OpenMP_CXX
	PRIVATE "$<LINK_LIBRARY:WHOLE_ARCHIVE,zendnnl::zendnnl_archive>")

Proposed fix:
By adding conditional logic to check for both library

if(TARGET zendnnl::zendnnl_archive)
  target_link_libraries(examples
    PUBLIC  OpenMP::OpenMP_CXX
    PRIVATE "$<LINK_LIBRARY:WHOLE_ARCHIVE,zendnnl::zendnnl_archive>")
elseif(TARGET zendnnl::zendnnl)
  target_link_libraries(examples
    PUBLIC  OpenMP::OpenMP_CXX
    PRIVATE zendnnl::zendnnl)
else()
  message(FATAL_ERROR "Neither zendnnl::zendnnl_archive nor zendnnl::zendnnl target found")
endif()

Impact
Examples cannot be built when using shared library
