AW: [CMake] Overriding default values

[Sören Freudiger]

May you just set a variable after the first configure by yourself:


CMakeList.txt:
-------------------
IF(NOT PASSED_FIRST_CONFIGURE)
   ADD_CXX_COMMAND("/wd4996")
   ADD_CXX_COMMAND("/ML")
   REMOVE_CXX_COMMAND("/MD")
ENDIF(NOT PASSED_FIRST_CONFIGURE)

...
SET(PASSED_FIRST_CONFIGURE)
--------------

this should work. but I would be happy if there already would be such an
variable odderd by CMake

Betreff: Re: [CMake] Overriding default values

Perhaps I should be more clear as to what I'm trying to do.

Is there a way to determine if CMake has been configured once for a given
project?

CMake obviously defines defaults for certain variables.  For example:

  CMAKE_CXX_FLAGS_RELEASE          -O2

Now, as the user, I can change this value with ccmake to be whatever I want,
and CMake will not change that ever once it has configured once.

All I want to do is offer a different default option that has the same
properties.  Once CMake configures the first time, CMake doesn't touch the
value again.

Thanks,
James
