[CMake] How to link a .so file under linux?

[Andy Cedilnik]

Hi Ning,

A quick solution would be to create symlink to your library:

FIND_FILE(MYLIB xxxxlib.so /path/to)
IF(NOT MYLIB)
  MESSAGE(SEND_ERROR "Cannot find library xxxxlib.so")
ENDIF(NOT MYLIB)
EXEC_PROGRAM(/bin/ln ARGS "-s \"${MYLIB}\"
\"${CMAKE_CURRENT_BINARY_DIR}/libxxxxlib.so\""
  RETURN_VALUE ln_res)
IF("${ln_retval}" GREATER 0)
  MESSAGE(SEND_ERROR "Problem creating symlink from 
\"${MYLIB}\" to \"${CMAKE_CURRENT_BINARY_DIR}/libxxxxlib.so\"")
ENDIF("${ln_retval}" GREATER 0)

TARGET_LINK_LIBRARIES(exec "${CMAKE_CURRENT_BINARY_DIR}/libxxxxlib.so")

Something like this should work.
