<p class=MsoNormal>cmake very nicely generates an HDF5-config.cmake file in the
build directory, and at install time, in the install directory. This is great.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>However, I have project A(paraview) with two subdirectories
B (hdf5) and C (mystuff), where C “uses” B. All is well except that
if C includes the hdf5-config.cmake from the Build directory as generated by B <span
style='font-size:8.0pt'>(ADD_LIBRARY(vtkhdf5 SHARED IMPORTED)) </span>, cmake
produces error messages along the lines of <o:p></o:p></p>

<p class=MsoNormal>Naturally, when building C standalone using the install
directory of standalone B, all works fine.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Everything would be simple, if cmake would simply skip the
imported target from B the second time it is loaded when called from the
subproject C, then a single set of config and cmakelists would work all the
time, but as it is, extra logic needs to be added.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Is there any easy way of telling project C, load the config file
if B is not part of the same build so that I can reuse the same syntax between
separate build or common builds. I’d like to use the generated
hdf5-config.cmake files because they have all the necessary properties set correctly
(like when target name is not the same as lib name etc etc, which makes things
harder like below). <o:p></o:p></p>
