Unable to create C++ bindings using instructions

[tanujthakkar]

Hey, I'm trying to build C++ bindings to use iceoryx2 in a C++ project. I followed the instructions here as well as in the quickstart guide link.

I am using a Jetson AGX Orin running Jetpack 5.1.1 and trying to build iceoryx2 v0.7.0

cmake -S . -B target/ff/cc/build
cmake --build target/ff/cc/build
cmake --install target/ff/cc/build --prefix target/ff/cc/install

After running the above commands, I added the following to my CMakeLists.txt,

list(APPEND CMAKE_PREFIX_PATH "/full/abs/path/to/target/ff/cc/install")
find_package(iceoryx2-cxx REQUIRED)
target_link_libraries(target iceoryx2-cxx)

I get the following error,

CMake Error at CMakeLists.txt:24 (find_package):
By not providing "Findiceoryx2-cxx.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"iceoryx2-cxx", but CMake did not find one.

Could not find a package configuration file provided by "iceoryx2-cxx" with
any of the following names:

iceoryx2-cxxConfig.cmake
iceoryx2-cxx-config.cmake

Add the installation prefix of "iceoryx2-cxx" to CMAKE_PREFIX_PATH or set
"iceoryx2-cxx_DIR" to a directory containing one of the above files. If
"iceoryx2-cxx" provides a separate development package or SDK, be sure it
has been installed.

If I remove those changes from the CMakeLists.txt, and add the following,

include_directories("/abs/path/to/iceoryx2/iceoryx2-cxx/include")
target_link_libraries(target
/abs/path/to/iceoryx2/target/ff/cc/install/lib/libiceoryx2_ffi_c.so
)

then I have a header include issue,

fatal error: iox2/publisher.hpp: No such file or directory
17 | #include <iox2/publisher.hpp>
| ^~~~~~~~~~~~~~~~~~~~

Hello @tanujthakkar,
thanks for using iceoryx2 and welcome. Building the iceoryx2 C++-Bindings is currently a bit more complicated because it has the iceoryx_hoofs as dependency which needs to be explicitly built together with the other components.
To accomplish that there is a guide to follow: https://github.com/eclipse-iceoryx/iceoryx2/tree/main/iceoryx2-cxx#build-instructions-for-integrator
We are currently working to integrate parts of iceoryx_hoofs directly into iceoryx2 as part of #1167, so that some of the build steps can be omitted. I have set a reminder to take a look at the documentation for improvements.

Thanks for the update @dkroenke ! As you mentioned, I followed the instructions here. I was on the main branch, and all the steps succeeded except the following step in the "Putting it together" section,

cmake --build target/ff/cxx/build

It is throwing compilation errors regarding headers in iceoryx2/target/ff/cc/install/include/iceoryx/v2.95.7/iceoryx_platform/ and iceoryx2/target/ff/cc/install/include/iceoryx/v2.95.7/iox/
