Passing LDFLAGS and CPPFLAGS to catkin_make

I want to use rosbridge on Mac OS X, which depends on rosauth, which in turn depends on libssl-dev

I've installed openssl on OS X via Homebrew, but it's keg-only since Apple uses its own libraries. Therefore, compilation of rosauth fails with:

[ 99%] Building CXX object rosauth/CMakeFiles/ros_mac_authentication_test.dir/test/ros_mac_authentication_test.cpp.o
[ 99%] Building CXX object rosauth/CMakeFiles/ros_mac_authentication.dir/src/ros_mac_authentication.cpp.o
/Users/smaniato/Cornell/Research/Projects/behaviors_ws/src/rosauth/src/ros_mac_authentication.cpp:15:10: fatal error: 'openssl/sha.h' file not found
#include <openssl/sha.h>

Homebrew says that I have to manually add the following build variables:

LDFLAGS:  -L/usr/local/opt/openssl/lib
CPPFLAGS: -I/usr/local/opt/openssl/include

How do I pass those to catkin_make? I tried the following but it didn't work:

catkin_make -D LDFLAGS=-L/usr/local/opt/openssl/lib CPPFLAGS=-I/usr/local/opt/openssl/include

I'm also OK with modifying CMakeLists.txt, since I'm building from source. Thanks!

I don't know how to pass this via command line.

If you want to adapt the CMakeLists.txt, you should be able to add the respective directories easily:

include_directories(/usr/local/opt/openssl/include)
link_directories(/usr/local/opt/openssl/lib)

make sure to add them before you create the respective targets.

However, imho it would be better to let this be handled by find_package, but I don't know if and how this works in OS X...

Thanks! I'll try adding those directories to CMakeLists.txt later today. I'll get back to you :-)
