Hi everyone,

i have a function like:

FUNCTION(checksyste_64Bit arg1)

    IF(CMAKE_SIZEOF_VOID_P EQUAL 8)

        SET(${arg1} TRUE PARENT_SCOPE)

ENDFUNCTION()


but when i call it with an INTERNAL variable i've set before with

SET(SYSTEM_64BIT FALSE CACHE INTERNAL)

checksystem_64bit(${SYSTEM_64BIT})

the ${SYSTE_64BIT} variable stays the same, i thought when i use PARENT_SCOPE on a variable i can change it's value from inside the function ?


best regards!
