[Brüns, Stefan <Stefan.Bruens@xxxxxxxxxxxxxx>]

Currently, the plugindir in the plugin manager is constructed as
{CMAKE_INSTALL_PREFIX}/bin/../{CMAKE_INSTALL_LIBDIR}/kicad/..., while
CMakes install uses {CMAKE_INSTALL_LIBDIR}/kicad/...

In case CMAKE_INSTALL_LIBDIR is a relative path "install" prefixes it
with CMAKE_INSTALL_PREFIX and both paths happen to match, otherwise
the constructed path ends up as e.g. "/usr/bin/../usr/lib/kicad/...".

For these cases where an absolute path is wanted CMake provides the
CMAKE_INSTALL_FULL_<dir> variants which works the same as
CMAKE_INSTALL_<dir> when used as DIRECTORY for install.

Fixes https://bugs.launchpad.net/kicad/+bug/1796905

Kind regards,

Stefan

Subject: [PATCH] Use absolute path CMAKE_INSTALL_FULL_LIBDIR for 3d viewer
 PLUGINDIR

Currently, the plugindir in the plugin manager is constructed as
{CMAKE_INSTALL_PREFIX}/bin/../{CMAKE_INSTALL_LIBDIR}/kicad/..., while
CMakes install uses {CMAKE_INSTALL_LIBDIR}/kicad/...

In case CMAKE_INSTALL_LIBDIR is a relative path "install" prefixes it
with CMAKE_INSTALL_PREFIX and both paths happen to match, otherwise
the constructed path ends up as e.g. "/usr/bin/../usr/lib/kicad/...".

For these cases where an absolute path is wanted CMake provides the
CMAKE_INSTALL_FULL_<dir> variants which works the same as
CMAKE_INSTALL_<dir> when used as DIRECTORY for install.
