[SOLVED] CMake illogic path parsing?

Issue

I'm trying to include this project into my cmake code base. I cloned the repo to my include/ dir and added this line to my CMakeLists.txtx:

add_subdirectory(${DIVISIBLE_INSTALL_INCLUDE_DIR}/cc.ublox.commsdsl)
include_directories(${DIVISIBLE_INSTALL_INCLUDE_DIR})
link_directories(${DIVISIBLE_INSTALL_INCLUDE_DIR})

But when I try to rebuild my project it says that it can't find the defined scheme files:

[WARNING]: failed to load external entity "/Users/pete/Documents/projekte/simple-dgps/dsl/main.xml"

If I add the project prefix(PROJECT_SOURCE_DIR) to the scheme files path the path appears twice.

ERROR: Failed to parse/Users/pete/Documents/projekte/simple-dgps/Users/pete/Documents/projekte/simple-dgps/include/cc.ublox.commsdsl/dsl/main.xml

And if I fill the missing part between simple-dgps and dsl (which would be include/cc.ublox.commsdsl) I get this error:

make[2]: *** No rule to make target `include/cc.ublox.commsdsl/include/cc.ublox.commsdsl/dsl/main.xml', needed by `output.tmp'.  Stop.
make[1]: *** [include/cc.ublox.commsdsl/CMakeFiles/cc.ublox.commsdsl.dir/all] Error 2
make: *** [all] Error 2

Assuming that the first error relates to a wrong file location, what does the second mean then(although it clearly has the wrong path because it exists twice)

Solution

Found the problem for the double path problem. I added the project as subdir from my main project by adding this line:

add_subdirectory(${DIVISIBLE_INSTALL_INCLUDE_DIR}/cc.ublox.commsdsl)

The problem is that DIVISIBLE_INSTALL_INCLUDE_DIR is a absolute path and thus is added to the cmake source dir of the subdir. This can be fixed by using:

add_subdirectory(include/cc.ublox.commsdsl)
