I just found that unless I explicitly include ExternalProject.cmak in my cmake build, cmake won't find command "ExternalProject_Add", which is pretty weird for me.<div>include(/usr/local/share/cmake-2.8/Modules/ExternalProject.cmake)</div>

Thanks, Luigi. However, I read the CMake 2.8 doc and tried to use function "ExternalProject_Add". When I ran cmake in the root of my project, I got the following error<div><br></div><div>Unknown CMake command "ExternalProject_Add"</div>
<div><br></div><div>I tried on both linux and mac and got the same error. And I am sure the version of the cmake is 2.8</div><div><br></div><div>Best,</div><div>Meng</div><div><div></div><div class="h5"><div><br><br><div class="gmail_quote">

Hello,<br>
Our project now uses a bunch of 3rd party libraries such as apr, protobuf, libcurl, etc. Almost all of these libraries use autoconf (<a href="http://configure.in" target="_blank">configure.in</a> <<a href="http://configure.in" target="_blank">http://configure.in</a>>) based build system. Since we have some modifications to most of the libraries, we have to integrate these libraries to our cmake build tree. What is the easiest way to integrate such a 3rd-party library to a cmake build with keeping the maximum portability?<br>

Try to look at ExternalProject module<br>

I have used it (with some mods): it allow to automate download pactch,build and install)<br>
Anyway, curl have recently included a CMakeLists in its distribution. I have used it even if had to apply some patches.<br>
I am trying to collect some cmake build recipes for some libraries I need.<br>
