Bug description

I'm attempting to build a snap based on core24 with the kde-neon-6 extension. It makes use of a bunch of library, but the one causing problems here is pugixml. I specify libpugixml-dev in the list of build-packages, however, a snapcraft pack fails with the error:

:: CMake Error at /snap/kde-qt6-core24-sdk/current/usr/lib/x86_64-linux-gnu/cmake/pugixml/pugixml-targets.cmake:111 (message):
::   The imported target "pugixml::static" references the file
::      "/snap/kde-qt6-core24-sdk/current/usr/lib/x86_64-linux-gnu/libpugixml.a"
::   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
::      "/snap/kde-qt6-core24-sdk/current/usr/lib/x86_64-linux-gnu/cmake/pugixml/pugixml-targets.cmake"
::   but not all the files it references.
:: Call Stack (most recent call first):
::   /snap/kde-qt6-core24-sdk/current/usr/lib/x86_64-linux-gnu/cmake/pugixml/pugixml-config.cmake:20 (include)
::   CMakeLists.txt:228 (find_package)

When I run with the --debug flag and look around, I can find the libpugixml.a file in /usr/lib/x86_64-linux-gnu but not in the /snap/... directory.

Steps to reproduce

  1. Obtain snapcraft.yaml file
  2. Run snapcraft pack

Environment

  • Ubuntu 24.04
  • LXD
  • Snapcraft not run in destructive mode

snapcraft.yaml
