Hello everybody,
there is a behaviour I do not understand when using cmake with -D option.
In my project I defined a few CACHE variables. One of them is GUI to
specify whether or not my project should be
built with graphical library support.
So in my main CMakeLists.txt I wrote something like:
SET(GUI FALSE CACHE BOOL "do the build in GUI mode")
PROJECT(crysfml Fortran)
...
When launching cmake with:
cmake -G "NMake Makefiles" -D CMAKE_Fortran_COMPILER=ifort -D GUI=TRUE
..\..\.
I always get the following message
#################################################################
GUI VALUE = TRUE
-- Configuring done
You have changed variables that require your cache to be deleted.
Configure will be re-run and you may have to reset some variables.
The following variables have changed:
CMAKE_Fortran_COMPILER= ifort
-- The Fortran compiler identification is Intel
-- Check for working Fortran compiler:
C:/Intel/Compiler/11.1/054/bin/ia32/ifort.exe
-- Check for working Fortran compiler:
C:/Intel/Compiler/11.1/054/bin/ia32/ifort.exe -- works
-- Detecting Fortran compiler ABI info
-- Detecting Fortran compiler ABI info - done
-- Checking whether C:/Intel/Compiler/11.1/054/bin/ia32/ifort.exe
supports Fortran 90
-- Checking whether C:/Intel/Compiler/11.1/054/bin/ia32/ifort.exe
supports Fortran 90 -- yes
GUI VALUE = FALSE
-- Configuring done
-- Generating done
-- Build files have been written to:
C:/Datas/Eclipse/workspace/crysfml/build/ifort_release_win
#################################################################
and the worse it that when deleting the cache and rebuilding it, the GUI
variable is switched to FALSE as you can see in the two MESSAGE commands
I put in my code (GUI VALUE =). Though, I would tend to think that the
-D command should have the last word.
There should be something I completely missed.
thanks a lot
see you
Eric
