polylineBlobsExample not compiling with glm 0.9.9.5

after updating glm to 0.9.9.5, ofPolyline does not compile anymore when used, because there is no matching function for call to ‘lerp(const vec3&, const vec3&, float&)’

I’m on Debian 10 (Buster), compiling with clang-8

PS: as the cause is the same of this other thread, should we make a single thread for testing and fixing glm 0.9.9.5 ?

or maybe it’s better to discuss this on a github issue ( i found more than one ) ?
