Here's how rosbuild does something similar, where PROJECT_NAME is an
unquoted string:
add_definitions(-DROS_PACKAGE_NAME='\"${PROJECT_NAME}\"')
Note the outer single quotes, and escaped double quotes. I suspect
that there are alternatives that would also work.
Btw, CMake usually takes -D definitions via add_definitions(), as in
this example. But adding them via rosbuild_add_compile_flags() will
also work.
