1) There is a regression in dev-libs/jsoncpp-1.9.6, see https://github.com/open-source-parsers/jsoncpp/issues/1568 and https://github.com/open-source-parsers/jsoncpp/pull/1570 2) I don't know enough about cmake and importing cpp interfaces to fix the cmake_modules/FindJsonCpp.cmake file to support finding jsoncpp by cmake module. So I've just falsified the test, so it falls back to using pkg-config to find jsoncpp (which is what it did before dev-libs/jsoncpp-1.9.6)
Does 1.9.6-r1 help?
Created attachment 904224 [details, diff] fixes build with newer dev-libs/jsoncpp-1.9.6 forced cmake to fail if it didn't find jsoncpp rather than passing jsoncpp-NOTFOUND to ninja added the macro that jsoncppConfig.cmake.meson is missing (upstream PR removes the call to the macro) short-circuited the cmake-module logic so that it falls back to using pkg-config to locate jsoncpp (I could not resolve "IMPORTED_LOCATION not set for imported target jsoncpp_lib")
(In reply to Sam James from comment #10) > Does 1.9.6-r1 help? nope - just more issues - but it would enable the patch to be trimmed a bit (dropping that check_required_components macro)

I forgot to scrub_patch those patches and to add comments to top. I've been fighting with cmake for 12 hours or so. Spectrum2 is running here and I'm going to have coffee and cake.
Created attachment 904228 [details, diff] build with dev-libs/jsoncpp-1.9.6-r1 using cmake module Third times the charm, now the patch is sourcing the jsoncpp cmake module. This requires the dev-libs/jsoncpp-1.9.6-r1 release (I've not tested rolling back to dev-libs/jsoncpp-1.9.5 and seeing if it builds / runs. It should, but I haven't tested) I'm not sure this is proper (and I'm not sure if upstream would be any wiser they appear to have sourced their FindJsonCpp.cmake from elsewhere). I also have no idea how a Windows machine would fare with patch.
*** Bug 940606 has been marked as a duplicate of this bug. ***
The garbage FindJsonCpp.cmake module in question appears to have come from https://github.com/rpavlik/cmake-modules and there are reports of other packages that fail to build for the same reason. You may want to somehow get that copy fixed and then propagate that update to dozens of arbitrary projects with vendored copies...
