--- Comment #4 from Tomasz Kłoczko <kloczko.tomasz at gmail.com> ---
Despite fact that you've been able to build WebKitGTK (I have no problems with libwpe, wpebackend-fdo and LTO) looks like 2.26.1 *is* broken.

WebKitGTK compiles and links correctly when using LTO is disabled.

I'm not fiddling in linker options to add -Wl,--no-undefined.
I'm using now as linker options:

$ rpm -E %build_ldflags
-Wl,-z,relro -Wl,--as-needed  -Wl,-z,now -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -flto -flto-partition=none -fuse-linker-plugin

If -Wl,--no-undefined is causing the issue it must be added by cmake.

Any suggestions?
