I'm running RHEL 5.1 and use gcc.

The following should be clean (using find_package) and work (the find module is called FindThreads):
cmake_minimum_required (VERSION 2.6)
find_package (Threads)
add_executable (myapp main.cpp ...)
target_link_libraries (myapp ${CMAKE_THREAD_LIBS_INIT})
target_compile_options solution above is wrong, it won't link the library.
Use:
SET(CMAKE_C_FLAGS_RELEASE "${CMAKE_C_FLAGS_RELEASE} -pthread")
OR
target_link_libraries(XXX PUBLIC pthread)
OR
set_target_properties(XXX PROPERTIES LINK_LIBRARIES -pthread)
