Public bug reported:
I tried to use this package when building VTK from source, by passing
the flag
-Dpugixml_DIR=/usr/share/libpugixml-dev/cmake
to the CMake configure step. This failed with
CMake Error at /usr/share/libpugixml-dev/cmake/pugixml-config.cmake:87
(message):
The imported target "pugixml" references the file
"/lib/x86_64-linux-gnu/libpugixml.so.1.8"
but this file does not exist. Possible reasons include:
* The file was deleted, renamed, or moved to another location.
* An install or uninstall procedure did not complete successfully.
* The installation package was faulty and contained
"/usr/share/libpugixml-dev/cmake/pugixml-config.cmake"
but not all the files it references.
Call Stack (most recent call first):
CMake/vtkModuleMacros.cmake:891 (find_package)
ThirdParty/pugixml/CMakeLists.txt:1 (vtk_module_third_party)
Looking at /usr/share/libpugixml-dev/cmake/pugixml-config.cmake, this
section of code:
# Compute the installation prefix relative to this file.
get_filename_component(_IMPORT_PREFIX "${CMAKE_CURRENT_LIST_FILE}" PATH)
# Use original install prefix when loaded through a
# cross-prefix symbolic link such as /lib -> /usr/lib.
get_filename_component(_realCurr "${_IMPORT_PREFIX}" REALPATH)
get_filename_component(_realOrig "/usr/lib/x86_64-linux-gnu/cmake/pugixml"
REALPATH)
if(_realCurr STREQUAL _realOrig)
set(_IMPORT_PREFIX "/usr/lib/x86_64-linux-gnu/cmake/pugixml")
endif()
unset(_realOrig)
unset(_realCurr)
get_filename_component(_IMPORT_PREFIX "${_IMPORT_PREFIX}" PATH)
get_filename_component(_IMPORT_PREFIX "${_IMPORT_PREFIX}" PATH)
get_filename_component(_IMPORT_PREFIX "${_IMPORT_PREFIX}" PATH)
get_filename_component(_IMPORT_PREFIX "${_IMPORT_PREFIX}" PATH)
if(_IMPORT_PREFIX STREQUAL "/")
set(_IMPORT_PREFIX "")
endif()
seems to arrive at a ${_IMPORT_PREFIX} of "", which means e.g.
set_target_properties(pugixml PROPERTIES
IMPORTED_LOCATION_NOCONFIG
"${_IMPORT_PREFIX}/lib/x86_64-linux-gnu/libpugixml.so.1.8"
IMPORTED_SONAME_NOCONFIG "libpugixml.so.1"
)
in /usr/share/libpugixml-dev/cmake/pugixml-config-noconfig.cmake will
become wrong ("/lib/x86_64-linux-gnu/libpugixml.so.1"), leading to
config error.
Looks like the calculation of ${_IMPORT_PREFIX} is wrong, not sure if
this is because of some wrong assumption that doesn't hold.
Seems to make it impossible to use this package from a CMake-using
project (using -Dpugixml_DIR).
