Create a shared library for dlib

Question

Following the instructions to compile dlib using cmake (here) generates a static dlib library:

cd examples
mkdir build
cd build
cmake ..
cmake --build . --config         


        

Answer 1

According to dlib/CMakeLists.txt, standalone (not from examples) building of dlib also creates shared library named dlib-shared:

mkdir shared_build # Build directory can be any
cd shared_build
cmake ..
cmake --build . --config Release
make install # Install library for make it acessible for others

For use this library in examples, you need to add definition of dlib library into your examples/CMakeLists.txt before include(../dlib/cmake).

examples/CMakeLists.txt:

...
PROJECT(examples)

add_library(dlib SHARED IMPORTED) # Imported(!) dlib target
set_target_properties(dlib PROPERTIES IMPORTED_LOCATION "")

# Now it is safe to include other dlib infrustucture - it won't build dlib again.
include(../dlib/cmake)
