I'm trying to use the Capstone disassembly framework in a C++ project on Ubuntu. I ran the following command to install the development package:
sudo apt-get install libcapstone-dev
This installed the includes in /usr/include/capstone but when I try to compile my application using the #include <capstone/capstone.h> include, I get linker errors:
undefined reference to `cs_open'
undefined reference to `cs_disasm'
undefined reference to `cs_free'
undefined reference to `cs_close'
These are all functions which should be implemented in the libcapstone.so.
Indeed, there is no libcapstone.so in the /usr/lib folder:

sudo apt-get install libcapstone2 does not work since the package is not found.
Is there any other package I need to install or maybe there is some simple CMake find_package() for Capstone? Resources I find do not seem to make the Capstone setup for linking against it/including it in a project straightforward enough.
EDIT:
The installed files by the libcapstone-dev package are:
$ dpkg-query -L libcapstone-dev

Capstone seems to provide pkg-config .pc file. So, the following should work:
include(FindPkgConfig)
pkg_check_modules (CAPSTONE REQUIRED capstone)
# Use CAPSTONE_FOUND, CAPSTONE_LIBRARIES, CAPSTONE_INCLUDE_DIRS vars
target_link_libraries(${PROJECT_NAME} ${CAPSTONE_LIBRARIES})
