Hi,
Von: James Bigler <[EMAIL PROTECTED]>
I have some optional code that runs and creates some variables
IF(MY_VAR)
SET(MY_OTHER_VAR 2)
ENDIF(MY_VAR)
If I turn off MY_VAR, I want MY_OTHER_VAR to do away like this:
IF(MY_VAR)
SET(MY_OTHER_VAR 2)
ELSE(MY_VAR)
DELETE(MY_OTHER_VAR)
ENDIF(MY_VAR)
SET(MY_OTHER_VAR)
or
SET(MY_OTHER_VAR FALSE)
should have the same effect, at least both will evaluate to false.
Is this good enough or do you need more ?
I want the variable to disappear from the list when running ccmake.
This didn't seem to do anything.
BTW, This is a more complete example:
FIND_PROGRAM(MY_EXECUTABLE
NAMES myproggy
PATHS )
IF(EXISTS ${MY_EXECUTABLE})
SET(FOUND_MY_PROGGY 1)
ELSE(EXISTS ${MY_EXECUTABLE})
SET(FOUND_MY_PROGGY 0)
# I want to remove MY_PROGGY from the ccmake display list
SET(MY_EXECUTABLE)
ENDIF(EXISTS ${MY_EXECUTABLE})
# You need at least version 2.4 for this to work.
IF("${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION}" LESS 2.4)
MESSAGE("You need at least version 2.4 for generating output. Go get
it from http://www.cmake.org/HTML/Download.html";)
SET(FOUND_MY_PROGGY 0)
# I really want to delete references to MY_EXECUTABLE
SET(MY_EXECUTABLE "")
ENDIF("${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION}" LESS 2.4)
Thanks,
James
