[cmake] Configure error with cmake 3.19.1 #42

Closed JackBoosY closed 3 years ago

JackBoosY commented 3 years ago

Hi guys, When I use cmake 3.19.1 configure simage, it shows:

-- Configuring done
CMake Error: install(EXPORT "simage" ...) includes target "simage" more than once in the export set.
-- Generating done

See https://github.com/coin3d/simage/blob/29d34eda95167f4e101d12e55394ddc731f03582/CMakeLists.txt#L663-L674

It export the target ${PROJECT_NAME} twice.

Hi Jack, thanks for notifying us. As this has worked for at least one and a half year without hassle I've started on the CMake discourse forum a thread as I think it's a regression in CMake. Let's see what the maintainers suggest and what further action we need to take. Cheers, Volker
