<p class="MsoNormal"><span style="color:#1F497D">Anytime John! I ran into the same problem as you when I tried to figure out a way to parse the arguments to my functions and/or macros. Because I couldn’t find the right documentation, I just went ahead and opened
up the module file itself (YourCMakeInstallPath/share/cmake-2.8/Modules/CMakeParseArguments.cmake). I have found from a lot of banging my head against the wall that sometimes it is just easier to look at the code itself. Typically, the module developers do
an excellent job of documenting the commands within the comments header of the file, and I have found that to be the easiest way to find exactly what I need to explain how to use it. Just as an example, here is the section in the CMakeParseArguments.cmake
file that explains what I explained to you:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#00B050"># As an example here a my_install() macro, which takes similar arguments as the<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#00B050"># real install() command:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#00B050">#<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#00B050"># function(MY_INSTALL)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#00B050"># set(options OPTIONAL FAST)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#00B050"># set(oneValueArgs DESTINATION RENAME)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#00B050"># set(multiValueArgs TARGETS CONFIGURATIONS)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#00B050"># cmake_parse_arguments(MY_INSTALL "${options}" "${oneValueArgs}" "${multiValueArgs}" ${ARGN} )<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">Do you happen to know what docs you were looking at? It may be worth a little bit to post that to this mailing list so that hopefully the person that wrote those docs could be so kind as to update them with the

<p class="MsoNormal" style="margin-left:.5in"><span style="color:#1F497D">The cmake_parse_arguments command takes 5 arguments, not 4. My guess is that you just need to get the arguments right and things should then work for you assuming the rest of your code
is correct. If you look in CMakeParseArguments.cmake you should see the documentation for the command, but I can tell you that the command takes the following arguments:<o:p></o:p></span></p>
<p class="MsoNormal" style="margin-left:.5in"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:.5in"><span style="font-family:"Courier New";color:#1F497D">cmake_parse_arguments(prefix options singleValueArgs multiValueArgs ${ARGN})<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-left:.5in"><span style="color:#1F497D">The prefix is what is added to the beginning of each variable that is set, the options is a list of parameters that do not have any arguments associated with them (i.e. REQUIRED, NO_DEFAULT_PATH,
etc.), the singleValueArgs is a list of all parameters that have only one argument associated with them, the mutliValueArgs is a list of all parameters that have one or more arguments associated with them, and the last parameter should always be ${ARGN}.<o:p></o:p></span></p>
