I use a technique like this:<div><br></div><div> configure_file(input ${CMAKE_CURRENT_BINARY_DIR}/proj-CMakeLists.txt @ONLY)<br> # or maybe COPYONLY instead of @ONLY if you have no replacements occurring</div><div><br>
ExternalProject_Add(proj</div><div> URL <a href="http://blah/blah/blah.tar.gz">http://blah/blah/blah.tar.gz</a></div><div> URL_MD5 md5-ofcourse</div><div> PATCH_COMMAND ${CMAKE_COMMAND} -E copy</div><div> ${CMAKE_CURRENT_BINARY_DIR}/proj-CMakeLists.txt</div>
<div> <SOURCE_DIR>/CMakeLists.txt</div><div> ...</div><div> )</div><div><br></div><div>That should work if your "proj" source comes from a .tar.gz file without a CMakeLists file in it, or with a CMakeLists.txt file that you want to overwrite with your own.</div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Thanks for the response on this, I was able to get this to work (to
degrees) with libtiff and Jasper as well as other non CMake-a-fied
projects. I have run into another issue where I wish to use
configure_file to generate a CMakeLists.txt file in the directory where
ExternalProject_add dumps the source and looks for the CMakeLists.txt
file. <br>
<br>
The problem is that I cannot configure_file at CMakeLists.txt.config
file into a CMakeLists.txt file in the source directory where
ExternalProject_Add will later look for it as ExternalProject_Add
removes the file and generates the error:<br>
<br>
CMake Error: The source directory
"D:/projects/glade/branches/glade_win_x64/source/libtiff" does not
appear to contain CMakeLists.txt.<br>
<br>
Clicking the Generate button in CMake creates the CMakeLists.txt file
and the ExternalProject_Add works just fine, but requires going back and
clicking generate in CMake<br>
<br>
I think my options are currently to run patch (not as powerful as
configure_file) using PATCH_COMMAND which as I recall is not in on Win
boxes and for which I have used GNUWin32 or possibly the
CONFIGURE_COMMAND. Maybe I should recursively call CMake to
configure_file the CMakeLists.txt file? <br>
<br>
Thanks,<br>
