<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">1) The top-level CMakeLists.txt you all have been working on is moved to CMakeLists.txt.old (the src/CMakeLists.txt file is untouched)<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">2) There is a Build_With_CMake.txt tutorial that shows the most important features and how to build libiomp5<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">3) As a special note, the current
<a href="http://build.pl" target="_blank">build.pl</a> system does five “micro-tests” which test certain features of the newly built libiomp5.so library (basic linking/compilation, library dependencies, etc.) If you want these to be off in the new CMake system
just specify it when calling cmake with the flag –Dtests=off<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Please keep in mind this is the initial system and that it can be trimmed back incrementally to what you need. Right now, it builds nearly identical libraries as
<a href="http://build.pl" target="_blank">build.pl</a>. On a related note, I attempted ( as suggested by David ) to port libiomp5 to NetBSD to see what walls I would hit. I hit some
<span style="font-family:Wingdings">J</span> , but eventually got it working (not included in this initial patch). So I am going to follow up this initial patch with further improvements (to the build system) to make re-targeting in general even easier. Some
of these improvements will also help the <a href="http://build.pl" target="_blank">
build.pl</a> system as well.<o:p></o:p></p>
