Hi all, I run into a compile error while installing Melodic on Debian9-- Stretch.

Basically, I followed the instructions here on a freshly installed Debian9 and had the following error when I was executing this cmd ./src/catkin/bin/catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release:

CMake Error at /home/parallels/ros_catkin_ws/devel_isolated/class_loader/share/class_loader/cmake/class_loaderConfig.cmake:148 (message):
Project 'class_loader' tried to find library '-lpthread'.  The library is
neither a target nor built/installed properly.  Did you compile project
'class_loader'? Did you find_package() it before the subdirectory
containing its code is included?

Reproduce this error by running:

A similar error was found here, but there's no effective solution to that problem.

What CMake version do you have? I ran into this with Gentoo not that long ago.

Mine is cmake 3.13.2. Will updating the cmake make a difference? Or there's a compatible version to compile it?

Try cmake < 3.13. That seemed to fix my issues on Gentoo. Still working on a patch for this.

Thanks for the suggestion. I'll give it a try!

I might have used the cmake 3.7.2 as when i used `apt-cache madsion cmake', it came out 3.7.2. But when I run cmake --version, it gave me 3.12.2.
