[CMake] CMake 2.8.8-RC2 with Mac OS X 10.7.3 Xcode 4.3.2

[Gary Little]

After beating my head against this brick wall for over a week I'm becoming convinced that the problem is neither with CMake nor with Boost. If I build the project as a Unix project or as a Visual Studio/nmake project, the created projects build fine whether it is for Linux, Darwin, or Windows. However, if I use CMake to build an Xcode project, then Xcode can NEVER find the boost header files that are located at "/usr/include/boost/...". The real kick in the head is if I use Xcode's project editing capabilities to add "/usr/include" to HEADER_SEARCH_PATHS it still cannot find the header files. If I then edit my header file from "<boost/random/uniform_int.hpp>" to "</usr/include/boost/random/uniform_int.hpp" it then finds the header file but then fails because that header include another file using "<boost/...".  

I dunno … I guess I was expecting Xcode to work as well as Visual Studio. It doesn't.

I have it to the point where using CMake 2.8.7 it would create the plethora of sub-project builds, build and link all of the dylibs that are used by Wish to run the diagnostics on the drives that we manufacture. Recently however, I realized I needed a better IDE than "vim", so I tried to run CMake to use Xcode 4.3.2. The first thing that happened was a CMake error which should be solved in CMake 2.8.8 RC1. It was, and CMake created the plethora of projects as well as the single xcodeproj file that ties them all together.

The warnings are nothing new, and like many shops we tend to ignore them … not my choice since I'm a bit anal about fixing warnings, but I have to live with these. However, I am not generating any dylibs, and when I go to a terminal and run "xcodebuild -project MyP.xcodeproj" I find that the build is actually failing with an error -- a Boost header file is not found.

My next thought was to go look at HEADER_SEARCH_PATHS, and sure enough "/usr/include" is not listed in that search path. I tried setting include_directores the CMakeLists.txt file governs the actual project that is being built but that does not work either. So, how do I set the search paths to find the Boost header files?
