=dev-libs/boost-1.81.0-r1 package somehow indirectly encodes -DCMAKE_BUILD_TYPE=Gentoo for boost cmake files. This causes cmake ebuilds that use EAPI=8 break on boost imports. Setting CMAKE_BUILD_TYPE=Gentoo as a workaround in the ebuild seems to work. I would say the need for such a workaround is a bug. Real world broken package is vcmi. Example workaround: https://github.com/trofi/slyfox-gentoo/commit/806a4a1d582348f7db23bf98a9cb12bbaabbb0aa Small reproducer that fails only on Gentoo from what I could test: // # cat ../foo.cc int main(){} # cat ../CMakeLists.txt cmake_minimum_required(VERSION 3.10.0) project(VCMI) set(CMAKE_BUILD_TYPE RelWithDebInfo CACHE STRING "Choose the type of build, options are: Debug Release RelWithDebInfo.

What is confising: configuration did not fail, but ninja.build encoded something invalid. The important bit here is invalid 'IMPORTED_LOCATION' setting for Boost components. Looks like the only provided location is GENTOORELEASE: # fgrep -R IMPORTED_LOCATION /usr/lib64/cmake |& fgrep -i boost |& fgrep -v GENTOORELEASE | wc -l 0 # fgrep -R IMPORTED_LOCATION /usr/lib64/cmake |& fgrep -i boost |& fgrep GENTOORELEASE | wc -l 72 Real world example is vcmi package.

can you give me an in-tree reproducer? I haven't seen any example of breakage like this.
I'm not aware of any in-tree examples.
