[CMake] General question about regex

[Steven Truppe]

I found the solution:

     get_cmake_property(_vars VARIABLES)
     foreach(_var ${_vars})
         string(TOUPPER ${lib} lib_upper)
         if(_var MATCHES "^WITH_LIB_${lib_upper}_EXAMPLE_([A-Za-z]+)$")
	        message(STATUS "Number of examples found: ${CMAKE_MATCH_COUNT}")
         	message(STATUS "Number 1 found: ${CMAKE_MATCH_0}")
         endif()

     endforeach()

Now i've two problem - the CMAKE_MATCH_0 contains the hole string and
not only the part the is in the (), i need only the part from the () -
is there another command i can use for this ?
