New ITT configuration breaks build on Castor

Question

[reported by dstark] [Trac time Fri Aug 27 18:33:32 2010] Using default GCC 4.4.2 on Castor, new ITT CMake setup is insufficient for setting the HPX_DONT_USE_ITT flag, thus breaking the build.

Not sure if ITT support is universal if compiling with an Intel compiler. Maybe cmake should accept a "-DHPX_USE_ITT" flag that would be supplied when the user knows they have that support, instead of trying to automate an opt-out policy.

[comment by hkaiser] [Trac time Fri Aug 27 18:43:49 2010] The current CMake configuration was intended to unconditionally disable ITT when not on Windows (mainly because I didn't try to make it work elsewhere yet). I don't understand why this does not work?

Here is what we currently have:

if(CMAKE_COMPILER_IS_GNUCXX OR (XIAR AND UNIX))   # gcc or Intel
# ...
    add_definitions(-DHPX_DONT_USE_ITT)
# ...
endif()

What\s wrong with it? Why does this break?
