I have a little question about how to prevent double substitution in an IF
statement.
Consider this macro that looks through a list for a string, and sets a
variable to TRUE if it is found. The problem I have is that the IF
statement substitutes ${VALUE2} with LIB, and then substitutes LIB with
HELLO, and finds what it's looking for, even though it wasn't really
there. I want it to stop at the first substitution to prevent this weird
behavior. Ideas?
MACRO(LIST_CONTAINS VAR VALUE)
SET(${VAR})
FOREACH(VALUE2 ${ARGN})
IF(${VALUE} STREQUAL ${VALUE2})
SET(${VAR} TRUE)
ENDIF()
ENDFOREACH()
ENDMACRO()
SET(LIB HELLO)
SET(LIBS LIB IS GREAT)
LIST_CONTAINS(CONTAINS_LIB ${LIB} ${LIBS})
MESSAGE(STATUS "CONTAINS_LIB = ${CONTAINS_LIB}")
