[develop2] PR 539 causing find_package to attempt to create the same target twice producing spurious warning

simonimpey opened this issue · comments

I am making the following find package call find_package(pugixml CONFIG REQUIRED) and since this PR I am seeing the following warning in the CMake output:

CMake Warning at x64/Debug/conan/build/Debug/generators/pugixmlTargets.cmake:25 (message):
  Target name 'pugixml::static' already exists.
Call Stack (most recent call first):
  x64/Debug/conan/build/Debug/generators/pugixml-config.cmake:16 (include)
  x64/Debug/conan_provider.cmake:303 (find_package)
  Common/FileIO/CMakeLists.txt:6 (find_package)

This cause by two things. Firstly the new behaviour in the conan_provider.cmake file is causing find_package to be called twice:

CMake Warning at x64/Debug/conan/build/Debug/generators/pugixmlTargets.cmake:25 (message):

Call Stack (most recent call first):

  x64/Debug/conan_provider.cmake:303 (find_package)
  Common/FileIO/CMakeLists.txt:6 (find_package)

Secondly the code in the generated pugixmlTargets.cmake file:

if(NOT TARGET pugixml::static)
    add_library(pugixml::static INTERFACE IMPORTED)
    set_property(TARGET pugixml::static PROPERTY INTERFACE_LINK_LIBRARIES pugixml::pugixml)
else()
    message(WARNING "Target name 'pugixml::static' already exists.")
endif()

I am uncertain if this is an issue with the new behaviour in conan_provider.cmake or something to do with the recipe generating a warning when it shouldn't. Should there potentially be a check in the conan_provider.cmake file e.g.

# Ensure that we consider Conan-provided packages ahead of any other,
# irrespective of other settings that modify the search order or search paths
# This follows the guidelines from the find_package documentation
#  (https://cmake.org/cmake/help/latest/command/find_package.html):
#       find_package (<PackageName> PATHS paths... NO_DEFAULT_PATH)
#       find_package (<PackageName>)

# Filter out `REQUIRED` from the argument list, as the first call may fail
set(_find_args "${ARGN}")
list(REMOVE_ITEM _find_args "REQUIRED")
if(NOT "MODULE" IN_LIST _find_args)
    find_package(${package_name} ${_find_args} BYPASS_PROVIDER PATHS "${CONAN_GENERATORS_FOLDER}" NO_DEFAULT_PATH NO_CMAKE_FIND_ROOT_PATH)
endif()
unset(_find_args)

# Invoke find_package a second time - if the first call succeeded,
# this will simply reuse the result. If not, fall back to CMake default search
# behaviour, also allowing modules to be searched.
if(NOT ${package_name}_FOUND)
    set(_cmake_module_path_orig "${CMAKE_MODULE_PATH}")
    list(PREPEND CMAKE_MODULE_PATH "${CONAN_GENERATORS_FOLDER}")
    find_package(${package_name} ${ARGN} BYPASS_PROVIDER)

    set(CMAKE_MODULE_PATH "${_cmake_module_path_orig}")
    unset(_cmake_module_path_orig)
endif()

Hi @simonimpey

Thanks for your report.
This is unexpected, we thought that CMake would be the one avoiding the duplicate call once the first time it has been found, in theory the manual if(NOT ${package_name}_FOUND) shouldn't be needed. We need to check this.
