Hello,
Consider the following case where:
- I want to export/import my library named mylib
- This library depends on OpenCV that is also exported
According to
http://www.cmake.org/cmake/help/v3.0/manual/cmake-packages.7.html#creating-packages
the CMakeLists.txt of my library is simpilar to:
project(mylib)
find_package(OpenCV)
add_library(mylib foo.c foo.h)
target_link_libraries(mylib ${OpenCV_LIBS})
...
export(EXPORT mylibTargets FILE
"${CMAKE_CURRENT_BINARY_DIR}/mylibTargets.cmake")
...
Now the CMakeLists of an other project that uses mylib will be like :
project(test)
find_package(mylib)
add_executable(test test.c)
target_link_libraries(test mylib)
During the build of this project the linker complains that OpenCV
libraries are not found
Linking C executable test
"/Applications/CMake 3.0.0.app/Contents/bin/cmake" -E cmake_link_script
CMakeFiles/test.dir/link.txt --verbose=1
/usr/bin/cc -Wl,-search_paths_first -Wl,-headerpad_max_install_names
CMakeFiles/test.dir/test.c.o -o test -lopencv_videostab -lopencv_video ...
ld: library not found for -lopencv_videostab
The problem comes from mylibTargets.cmake where I have:
set_target_properties(mylib PROPERTIES
IMPORTED_LINK_INTERFACE_LIBRARIES_NOCONFIG
"opencv_videostab;opencv_video;..."
IMPORTED_LOCATION_NOCONFIG "/tmp/build/libmylib.dylib"
IMPORTED_SONAME_NOCONFIG "/tmp/build/libmylib.3.dylib"
)
while I wanted to have the full path to OpenCV libraries (ie
/tmp/OpenCV/lib/libopencv_videostab.2.4.10.dylib ...
Is there a proper way to include OpenCV dependencies during the export
of my library ?
Fabien
