I'm not explicitly specifying libtiff as a dependency in the CMakeLists.txt
for my project.

target_link_libraries(${PROJECT_NAME} PRIVATE
"${ADDITIONAL_LIBRARY_DEPENDENCIES}")
get_target_property(OUT ${PROJECT_NAME} LINK_LIBRARIES)
message(STATUS "Link libraries: " ${OUT})
and the configure step outputs this:
1> [CMake] Configuring project: DeepSkyStacker
1> [CMake] -- Link libraries:
Qt6::CoreQt6::CoreQt6::WidgetsQt6::NetworkDeepSkyStackerKernellibrawZClass$<
$<CONFIG:Debug>:tiff.aexiv2.aexpat.az.acfitsio.a>$<$<CONFIG:Release>:tiff.ae
xiv2.aexpat.az.acfitsio.a>
Which looks correct to me. But when I get to the link step of my build, the
critical part of the link command reads:
-Bstatic -ltiff -lexiv2 -lexpat -lz -lcfitsio . stuff deleted .
-llibtiff
So where is that -llibtiff coming from?? Is there something in the headers
that could cause that?
Thanks, David
