Why without use flags static-libs the ebuild not install the headers?
Because it doen't install the library otherwise, which is only a .a.
Yes, NVCtrl headers are for using libXNVCtrl.a which isn't installed without USE=static-libs (no shared version), I don't quite see what use the headers will have without the library.

Obviously if you remove the USE flag and install it unconditionally, they'll always be installed. I think you're asking "why not remove the flag and always install these?"

and in any case there are libraries like clang or others that install static archive even if they are build shared
Again, the headers are /not/ useful without the static archive that USE=static-libs is installing. Installing /just/ the headers does /not/ allow hwloc to build with VIDEO_CARDS=nvidia. You'll get: checking for NVCtrl/NVCtrl.h... yes (header is found) checking for XNVCTRLQueryTargetAttribute in -lXNVCtrl... no (static archive is missing) configure: WARNING: Specified --enable-gl switch, but could not configure: WARNING: find appropriate support configure: error: Cannot continue (failed) In the test where you removed the condition, you still installed the static archive through: dolib.a nvidia-settings/src/out/libXNVCtrl.a So it was the equivalent of having USE=static-libs enabled (note that it'd also fail if you had USE="-tools -static-libs" because the library wouldn't have been built at all).
The bug has been referenced in the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=c3baa0907a981c1d0046451668e6b9d8c316d86e commit c3baa0907a981c1d0046451668e6b9d8c316d86e Author: Ionen Wolkens <ionen@gentoo.org> AuthorDate: 2022-03-28 15:56:01 +0000 Commit: Ionen Wolkens <ionen@gentoo.org> CommitDate: 2022-03-28 16:11:15 +0000 x11-drivers/nvidia-drivers: enable static-libs USE by default Now that hwloc depends on this by "default" when VIDEO_CARDS=nvidia, not being enabled by default tend to be an annoyance. This only has a cheap build-only dependency on libX11/Xext, is tiny, and doesn't take long to build. Only makes some sense to disable if wayland-only or headless without X (albeit this is why the USE exists and isn't unconditional, /could/ be merged with USE=X although that USE has more implications.. may revisit later).
