exclude IlmImf/b44ExpLogTable.cpp from the build,
it's used originally to generate IlmImf/b44ExpLogTable.h, but not nessecary for the library.(probably only here for documentation
when included with static linking it introduces a problem with multiple definitions of main()
file(GLOB lib_hdrs Half/*.h Iex/Iex*.h IlmThread/IlmThread*.h Imath/Imath*.h IlmImf/*.h)
list(APPEND lib_hdrs "${CMAKE_CURRENT_BINARY_DIR}/IlmBaseConfig.h" "${CMAKE_CURRENT_BINARY_DIR}/OpenEXRConfig.h")
