Compile Problem on Ubuntu #137

Thanks for writing this program, I hope that I can successfully use it :)

I got some problems when compiling it on Ubuntu, so issue them to ask for help :P

Firstly I tried the examples/submodule/ directly after the licensecc installed. I executed cmake .. -DCMAKE_INSTALL_PREFIX=. in path examples/submodule/build, which is descibed in README. Then I got this output.

/home/ubuntu/projects/license-demo/examples/submodule/extern/open-license-manager
-- Found PkgConfig: /usr/bin/pkg-config (found version "0.29.1") 
-- LicenseCC found licensecc_DIR-NOTFOUND
-- Configuring done
CMake Error at CMakeLists.txt:20 (add_executable):
  Target "example" links to target "licensecc::licensecc_static" but the
  target was not found.  Perhaps a find_package() call is missing for an
  IMPORTED target, or an ALIAS target is missing?

It seemd that the program cannot located where the licensecc was. So I put the files of licensecc in exmaples/submodule/extern/open-license-manager/.

Then the output was

So why does it cannot found the licensecc_DIR? How can I fix it?

Thanks for reading and looking forward to the reply :)
