AW: [Insight-users] building insight applications for release

[Luis Ibanez]

Hi Zein

The configuration type (Debug/Release) in windows
cannot be selected from CMake.  You have to do this
from VC++.

Your problem is probably originated from FLTK.

The reason is the following: for ITK and VTK
(and most other packages, VC++ will generate code
in independent directories (/Debug, /Release).

Thanks to these independent directories, CMake can
figure out how to build your application and link
the appropriate version (debug/release) of the
VTK and ITK libraries.

For FLTK however, this is not possible because the
filenames of the libraries have been hand-selected
with this non-standard "d" suffix.

    fltk.lib    ==   Release
    fltkd.lib   ==   Debug

With this naming convention CMake cannot switch
from Debug to Release versions of FLTK. It is stuck
with the filenames you provided during your configuration.
Those filenames got hardcoded in the CMakeCache.txt file
and do not change when you switch from Debug to Release.



We will throw a party at Kitware the day FLTK starts
using CMake for their build process instead of using
their non-standard hand-crafted VC++ project and
hand-crafted Makefiles.

It is unfortunate that such a nice toolkit (FLTK)
results in so many colateral configuration problems
for the final applications. Too many bytes of the
ITK-users list have been spent on FLTK related issues.

-----

BTW, the solution to your problem is to build
your application in two different binary directories.
One will be dedicated to the Release version, the
other to the Debug version. When you run CMake to
configure each one, make sure that you provide the
non-"d" FLTK library names for the Release binary
directory, and that you provide the "d" FLTK library
names for your Debug application binary directory.
This will take as much disk space as the natural
VC++ mechanism of creating Debug/Release subdirectories
in the final leaves of the directory structures.


If you have any complains about this,...
Please send them to the FLTK users-list
and tell them about CMake,  http://www . cmake . org   :-)



    Regards,


       Luis
