Re: Orocos integration in buildroot

[snip]

I managed to build rtt and ocl. I still have one issue : my ROS_ROOT
is defined because I have my standard developpment toolchain there in
a ROS build system. But when I build with Buildroot, I have my
CMAKE_INSTALL_PREFIX that is "forced" by this (in rtt/CmakeLists.txt)
:

# We force it in case of ROS builds because the UseOrocos.cmake
scripts will always look
# in this path, also during an autoproj/bootstrap build.
IF(ROS_ROOT)
  SET(CMAKE_INSTALL_PREFIX
    ${PROJECT_SOURCE_DIR}/../install CACHE PATH "Orocos install prefix
for ROS builds" FORCE
    )
[snip] ...

  endif()
ENDIF(ROS_ROOT)


In the best world, I would like to set something in CMake cache to ask
it not to take ROS_ROOT into account, are you interested in such a
feature ?
In the worst world, I have to unset ROS_ROOT locally before building
with Buildroot. The problem is that I don't really have a way to
automate this, so if someone use buildroot with ros it will fail.
