Cannot find a way to install Clang libs for irony

[Encorpluptit]

Hi,

I'm on Fedora 30, and like many i have problems with clang libs when trying to use the command in emacs: irony-install-server. I got the error message below.

I couldn't find clang libs and header via updatedb and locate. About a week about i tried by myself to reinstall llvm and clang for getting those libs/headers. Ended up broking my Fedora 28. llvm, llvm-libs, clang, clang-libs are installed and i can't find anything to help me resolve this.

How can i install those ?

Could not find a package configuration file provided by "Clang" with any of the following names:

ClangConfig.cmake
clang-config.cmake

Add the installation prefix of "Clang" to CMAKE_PREFIX_PATH or set "Clang_DIR" to a directory containing one of the above files. If "Clang" provides a separate development package or SDK, be sure it has been installed.

Ok I found, sorry. After 10h trying things by myself, I found it 5 mins after posting this.
