Malformed gz-tools2-all CMake config package installed by gz-tools

[traversaro]

While working on the conda-forge Jetty update, I noticed that gz-tools2 installs a malformed CMake config file, see for example in apt packages:

traversaro@IITBMP014LW012:~/gzcondaws/gz-tools2-feedstock$ apt list --installed | grep gz-tools2

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

gz-tools2/unknown,now 2.0.3-1~noble amd64 [installed]
libgz-tools2-dev/unknown,now 2.0.3-1~noble amd64 [installed,automatic]
traversaro@IITBMP014LW012:~/gzcondaws/gz-tools2-feedstock$ cat /usr/lib/x86_64-linux-gnu/cmake/gz-tools2-all/gz-tools2-all-config.cmake
# - Config to retrieve all components of the gz-tools2 package
#
# This should only be invoked by gz-tools2-config.cmake.
#
# To retrieve this meta-package, use:
# find_package(gz-tools2 COMPONENTS all)
#
# This creates the target gz-tools2::all which will link to all known
# components of gz-tools2, including the core library.
#
# This also creates the variable gz-tools2_ALL_LIBRARIES

# Get access to the find_dependency utility

# Find the core library
find_dependency(gz-tools2 2.0.3 EXACT)

Why it is malformed? As now gz-tools2 CMake config package is installed, the find_dependency(gz-tools2 2.0.3 EXACT) call will always fail. Probably it could make sense to avoid to install any CMake config package at all.

Environment

• OS Version: Ubuntu 24.04
• Source or binary build?
