# since now (wioth cmake 2.6) just the full RPATH is used always for everything.
# It does create wrapper shell scripts for the executables.
# It overrides the defaults set in FindKDE4Internal.cmake.
# For every executable a wrapper script is created, which sets the appropriate
# environment variable for the platform (LD_LIBRARY_PATH on most UNIX systems,
# DYLD_LIBRARY_PATH on OS X and PATH in Windows) so  that it points to the built
# but not yet installed versions of the libraries. So if RPATH is disabled, the executables
# can be run via these scripts from the build tree and will find the correct libraries.
# If RPATH is not disabled, these scripts are also used but only for consistency, because
# they don't really influence anything then, because the compiled-in RPATH overrides
# the LD_LIBRARY_PATH env. variable.

# add a  manifest file to executables.
#
# There is a henn-egg problem when a target runtime part is renamed using
# the OUTPUT_NAME option of cmake's set_target_properties command.
#
# At now the Makefiles rules creating for manifest adding are performed
# *after* the cmake's add_executable command but *before* an optional
# set_target_properties command.
# This means that in KDE4_ADD_MANIFEST the LOCATION property contains
#  the unchanged runtime part name of the target. :-(
#
# The recently used workaround is to specify a variable build off the target name followed
# by _OUTPUT_NAME before calling kde4_add_executable as shown in the following example:
#
# set(xyz_OUTPUT_NAME test)
# kde4_add_executable( xyz <source>)
# set_target_properties( xyz PROPERTIES OUTPUT_NAME ${xyz_OUTPUT_NAME} )
#
# The full solution would be to introduce a kde4_target_link_libraries macro and to
# call KDE4_ADD_MANIFEST inside instead of calling in kde4_add_executable.
# This would require patching of *all* places in the KDE sources where target_link_libraries
# is used and to change the related docs.
#
# Because yet I found only 2 locations where this problem occurs (kjs, k3b), the workaround
# seems to be a pragmatically solution.
