Fix #7968
The upstream
CMakeLists.txt
for libpng exports targets to a file namedlibpng16.cmake
.However,
find_package(libpng CONFIG)
expects a file namedlibpngConfig.cmake
to exist instead.In order for
find_package(libpng CONFIG)
to work, we create a file with the proper name (libpngConfig.cmake
) that includes the one generated by the build (libpng16.cmake
).Note: CMake provides a module to find
libpng
by callingfind_package(PNG)
