[CMake] yaml-cpp error

[esatgundogdu]

I have tried to compile ompl from latest commit source files, but it gives cmake error. Then I also tried version 1.6.0 source files and everything was fine. I think there is an issue with commits after 1.6.0 version.

Here what I tried to do and the results:

git clone https://github.com/ompl/ompl.git
cd ompl
mkdir -p build/Release
cd build/Release
cmake ../..

After this, I got this error:

CMake Error at demos/CMakeLists.txt:67 (add_library):
  add_library cannot create ALIAS target "yaml-cpp::yaml-cpp" because target
  "yaml-cpp" is imported but not globally visible.

My system is Ubuntu 20.04 and as I said before, ompl version 1.6.0 was successfully compiled.
