I'm trying to create a catkin wrapper to build a library from external files. I'm usually using catkin_simple. However, the header files here are not contained in the include directory. I'm trying to figure out where to install them so that I can use #include <AdsLib/AdsLib.h> in other catkin packages to use this library.

Looking at catkin_simple's cs_install macro, I tried to add my header files. However, other packages can still not find the includes.

Edit: The files exist in install/include. But it seems like the build system is looking for them in the devel or source space. Since catkin_simple is only including from the include folder, I tried to add catkin_package(INCLUDE_DIRS ${SOURCE_DIR}/AdsLib). But the command is executed before the external project folder is cloned, which leads to an error.

What am I missing?

CMakeLists.txt:

cmake_minimum_required(VERSION 2.8.3)
project(ads_catkin)

find_package(catkin_simple REQUIRED)
catkin_simple()

include(ExternalProject)

I switched to the DownloadProject Cmake module, which works perfectly fine now: https://github.com/Crascit/DownloadPr...

The problem was that the steps from cs_export were executed before the source code was downloaded.
