Dear ceres_catkin friends,

As a newbie in ceres, we have no idea where we should put ceres_catkin and its dependencies in order to execute catkin_make successfully. Could you give us a little bit more tutorial ? For example, shall we put all of them under /src or directly under root workspace ?

Also, https://github.com/ethz-asl/catkin_simple is not available, we are using an alternative: https://github.com/catkin/catkin_simple

Thank you,

Just tried to use the package on a clean 16.04 installation.
However, ceres doesn't find the Suitesparse headers, since ${CATKIN_DEVEL_PREFIX} is pointing to the .private directory.

The solution for me are these two changes:
ceres_catkin/CMakeLists.txt

-    -DSUITESPARSE_INCLUDE_DIR_HINTS=${CATKIN_DEVEL_PREFIX}/include/suitesparse 
+    -DSUITESPARSE_INCLUDE_DIR_HINTS=${suitesparse_INCLUDE_DIRS}

suitesparse/CMakeLists.txt

-    INCLUDE_DIRS include ${SUITESPARSE_INCLUDE_DEST}
+    INCLUDE_DIRS ${SUITESPARSE_INCLUDE_DEST}

See #13

Hi!
I am trying to use ceres, but when building it, I get the following error:

CMake Error at gflags_catkin/CMakeLists.txt:4 (find_package):
By not providing "Findcatkin_simple.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"catkin_simple", but CMake did not find one.
I actually tried to build ceres without pulling the following git repository because the link is broken.
https://github.com/ethz-asl/catkin_simple
Could you please make it available again?

Thanks in advance,

I was working with this package in a workspace and invoked rosdep install with the --from-path option and it could not resolve the blas rosdep key.

There's a similar rule here: https://github.com/ros/rosdistro/blob/master/rosdep/base.yaml#L1300-L1304

And there's Atlas: https://github.com/ros/rosdistro/blob/master/rosdep/base.yaml#L200 which is also a dependency.

It successfully built after running rosdep install --from-path . -iy --skip-keys blas which suggests that this dependency declaration might be unnecessary.
