<br>
Concerning the issues in the enclosed message, I guess I found
what I should change to make ITK import the GDCM library paths.
Patching ITK_SOURCE_DIR/Modules/ThirdParty/GDCM/CMakeLists.txt
as below<br>
<br>
###<br>
if(ITK_USE_SYSTEM_GDCM)<br>
set(ITKGDCM_SYSTEM_INCLUDE_DIRS<br>
${GDCM_INCLUDE_DIRS}<br>
)<br>
set(ITKGDCM_INCLUDE_DIRS ${GDCM_INCLUDE_DIRS})<br>
+ set(ITKGDCM_SYSTEM_LIBRARY_DIRS ${GDCM_LIBRARY_DIRS})<br>
set(ITKGDCM_LIBRARIES ITKGDCM)<br>
else()<br>
###<br>
<br>
updated ITK_GDCM_LIBRARY_DIRS with the correct value. Would
anyone know if this is indeed the right place for the change? <br>
Thanks again,<br>
Rômulo<br>

I'd like to bring back the thread <a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="http://www.itk.org/pipermail/insight-users/2011-December/043218.html">http://www.itk.org/pipermail/insight-users/2011-December/043218.html</a>,
because it seems to me that there is still something broken in
ITKv4 comipilation with ITK_USE_SYSTEM_GDCM (GDCM 2.x).<br>
<br>
Despite the corrections made in <a moz-do-not-send="true"

I find it strange that we must make-install GDCM even if we're
compiling/linking ITK with GDCM's build tree (as described in
the thread above). The make-install solution only works if the
installation folder is a "system" folder, which is added to
the link directives by default. I think it's even a dangerous
solution if we are, eg, testing a new GDCM version and trying
to link with its own build tree, while "silently" linking with
an old (previously make-installed) version, since the latter
is the one the linker will actually find. <br>
<br>
Patching
ITK_SOURCE_DIR/Modules/ThirdParty/GDCM/itk-module-init.cmake
as below <br>
<br>
###<br>
option(ITK_USE_SYSTEM_GDCM "Use an outside build of GDCM."
OFF)<br>
mark_as_advanced(ITK_USE_SYSTEM_GDCM)<br>
<br>
if(ITK_USE_SYSTEM_GDCM)<br>
find_package(GDCM REQUIRED)<br>
+ include(${GDCM_USE_FILE})<br>
endif()<br>
###<br>
<br>
seems to solve the problem.<br>
<br>
However, ITKConfig doesn't import the library paths exported
by GDCM, so in the end I get "-lgdcmXXX not found" erros when
linking my program with ITKv4 + (a non-make-installed)
SYSTEM_GDCM. After building ITK, I noticed that </font></font><font
size="-1"><font face="Arial"><font size="-1"><font face="Arial">ITKGDCM_LIBRARY_DIRS
is empty </font></font>in (BUILD or
INSTALL)_DIR/lib/cmake/ITK-4.2/Modules/ITKGDCM.cmake, in
contrast with ITKGDCM_INCLUDE_DIRS, which does contain the
right paths (i.e., those exported by GDCM). Manually updating
</font></font><font size="-1"><font face="Arial"><font size="-1"><font
face="Arial"><font size="-1"><font face="Arial">ITKGDCM_LIBRARY_DIRS
does solve the problem, but I'm not a cmake expert and
couldn't find which file(s) should be patched so that
things work as I would expect. <br>
<br>
Does anyone have faced this problem as well?<br>
Kind regards,<br>
