Bug 756760 – media-libs/simage and media-libs/coin cannot build with cmake >= 3.19

• Status: RESOLVED DUPLICATE of bug 759271
• Product: Gentoo Linux

[Description ppdplayer 2020-11-25 18:51:48 UTC]

Both packages had a similar error during the generation step in configuration. 

CMake Error: install(EXPORT "Coin" ...) includes target "Coin" more than once in the export set.

This makes the package unable to build. This was fixed by using a cmake with a version < 3.19.

Reproducible: Always

Is it cmake or packages that need to be fixed here? If the latter then maybe this need a tracker? (+ individual bugs)

I feel there may(?) be many affected packages that will slowly keep being found.

From a quick look I also see bug #756325 and bug #755932 with same EXPORT error.

Not ::gentoo but I also seen someone run into this with sci-libs/itk-5.1.0::science

There should probably be a tracker for this.

It was the former and considered a regression[0], should be fixed in cmake-3.19.2
