It's because CMake is a 32-bit app running on Win64. Windows itself reports to a 32-bit app that "kernel32.dll" is in C:/Windows/System32, even though the one that's really loaded into a 32-bit app is actually located at C:/Windows/SysWOW64.<br>

<p class="MsoNormal">I'm using the 'fixup_bundle' capability for generating my installation package, but GetPrerequisites fails for a specific file, which is in C:/Windows/System32. Other files in
C:/Windows/System32 are found just fine. I've detected that the problem is specifically with the find_file() call.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal"># Example Code that illustrates the problem</p>
<p class="MsoNormal">set (myfiles</p>
<p class="MsoNormal"> kernel32.dll</p>
<p class="MsoNormal"> mpich2mpi.dll

<p class="MsoNormal"> "C:/TEMP"</p>

<p class="MsoNormal">foreach(file ${myfiles})</p>
<p class="MsoNormal"> set(rt "rt-NOTFOUND")</p>

<p class="MsoNormal">endforeach(file)</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Ouput:</p>
<p class="MsoNormal">FILE: kernel32.dll; RT: C:/Windows/System32/kernel32.dll</p>
<p class="MsoNormal">FILE: mpich2mpi.dll; RT: rt-NOTFOUND</p>
<p class="MsoNormal">FILE: testfile.txt; RT: rt-NOTFOUND</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">If I copy mpich2mpi.dll and testfile.txt to C:/TEMP, the find_file() call will find the files in C:/TEMP.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">So my question is why does find_file NOT find mpich2mpi.dll in System32, but it can find it in C:/TEMP. Does find_file treat the System32 directory special somehow? Is there a
recommended work around to this issue?</p>
