Hi,
as mentioned in issue #523 when including CRPropa over
add_subdirectory
in other projects, the relative paths are not pointing to the correct folders.To better support CRPropas behavior when included elsewhere, I changed all relative paths to the correct absolute paths utilizing
CMAKE_CURRENT_SOURCE_DIR
andCMAKE_CURRENT_BINARY_DIR
respectively.I also added a new cache variable for
CRPROPA_EXTRA_INCLUDES
so the include paths can be used on the above levels (I do not know how to hide this from the user if possible).
