Hi,

I created a custom library in my package pack_A like so:

...
catkin_package(
   INCLUDE_DIRS include
   LIBRARIES mycustomlib
#  CATKIN_DEPENDS 
#  DEPENDS
)

add_library(mycustomlib STATIC src/customsource.cpp)
target_link_libraries(mycustomlib ${other_libs})
...

And then in another package, I include pack_A and try to explicitly link against mycustomlib it instead of using {catkin_LIBRARIES} like so:

... 
find_package(catkin REQUIRED COMPONENTS pack_A) 
add_library(liblinktest src/test.cpp) 
target_link_libraries(liblinktest mycustomlib) 
...

However I get the error:

error: cannot find -lmycustomlib

Can anyone help me out? I do not want to link against {catkin_LIBRARIES}. Thanks for your time.

EDIT: This... actually does build. However, I've been developing within QtCreator, and for some reason I get the "cannot find ..." error in QtCreator, but when I build via catkin_make, it builds just fine and runs.

Does anyone know why there is such a discrepancy between QtCreator and catkin_make here?

link_directories( /path/to/my/custom/lib )
