Description Duncan 2020-07-22 12:49:10 UTC 
Upstream kpat commit e9ceec479 toggled the black-hole solver (for the golf module) ON by default, so now a kpat build fails with:

-- Checking for module 'libfreecell-solver'
--   Found libfreecell-solver, version 5.24.0
-- Checking for module 'libblack-hole-solver'
--   No package 'libblack-hole-solver' found
CMake Error at /share/cmake/Modules/FindPkgConfig.cmake:497 (message):
A required package was not found
Call Stack (most recent call first):
/share/cmake/Modules/FindPkgConfig.cmake:681 (_pkg_check_modules_internal)
CMakeLists.txt:18 (pkg_check_modules)

(It's /share/... not /usr/share/... because I have reverse-usr-merge /usr -> . )

A quick emerge --search for black-hole suggests the library isn't in-tree (or kde overlay) so hard-toggling the option off is likely the best short-term fix until a package is available.  Since the black-hole-solver's apparently only useful for the golf module, assuming the solver's eventually packaged, perhaps a USE flag is in order for those who would prefer to avoid the dep.

(FWIW, my easiest quick-fix was effectively git show -R e9ceec479 > /etc/portage/patches/kde-apps/kpat/no-black-hole-solver.patch .)
