error during install melodic version

[benbenji]

Hi when I tried to install the melodic version of ecl_core the output shows that problem:
CMake Error at ecl_core/ecl_linear_algebra/CMakeLists.txt:29 (get_target_property):
get_target_property() called with non-existent target "Sophus::Sophus".
I use the melodic version of sophus
did any gays meet this problem ? I will appreciate it very much if you can give me a solution

Did you use the binaries or the release branches (make sure you're not using the devel branches anywhere)?

Aging out.
